A Closer Look at Snow Leopard's Wake on Demand Feature

I'm the same... I want to use whatever router I like. And I do. And I wake it wirelessly. Is easy with this app. http://www.doogul.com/software/wom/
This is great! Now I can leave my MacBook asleep all day and it wakes up perfectly from my iPhone via VNC 
The "green company" forgot to add some notes about power usage. Not good.
Also, from Apple's document:
"To use Wake on Demand wirelessly with a WPA or WPA2 network, the AirPort base station or Time Capsule must be hosting the network."
Please note that WPA (with TKIP) has been cracked – 'hackers' do this in a few seconds – yet there's no word about (additional) security (features) in Apple's documents. In short; You should be using WPA2 with AES only, or not use this feature at all.
Ah, this part is very interesting:
"Macs that have Wake on Demand enabled will occasionally wake for a brief time, without lighting the screen, in order to maintain registrations with the Bonjour Sleep Proxy. On some Macs, sounds from the optical drive, hard drive, or fans may be heard during these brief maintenance wakes.".
And that will most definitely take some power. Not to mention the annoying sound, for people sleeping next to their Mac's

Shut lid on portables?
Ok, I'm curious:
What would happen if I put my MBP to sleep by shutting the lid, then tried waking it over LAN / WLAN? Does the whole OS start up, or just the sharing services? What about if the computer requires a password to wake from sleep?
Hmm.

True. I've made that clear now. Thanks!
I was however just trying to address the absence of notes about these kind of security issues – as a reminder
Closing the lid won't work (apparently, but I haven't checked it myself):
"Additionally, portable Macs with Wake on Demand enabled will only wake on demand if they are plugged into power and either the built-in display is open or an external display is attached. "
And it will wake the whole OS:
"Any client that connects to one of these services (as in Bonjour-registered services) will cause the Snow Leopard Mac to wake."
And back to sleep:
"Once that request is complete, the Mac will go back to sleep at its regularly-scheduled interval as set in the Computer Sleep section of the Energy Saver preferences pane."
Seems like your sleep setting is rather important for this feature (in order to be green).
No word about passwords however!
Note: This still rather fresh document – currently a first draft – might be changed in the near future and explain some things a little more. Hopefully.
So, would there be a way to make this work over WAN? I like to be able to connect to my Mac at home from work using the MobileMe BackToMyMac. I know if is just doing a global bonjour thing. I assume I can't wake my Mac over the WAN, but I'd be interested to hear anyone give explanations otherwise.
Why wouldn't it work? I haven't tested the scenario you describe, but I have been able to wake my Macbook via SSH from an iPhone connected to AT&T's 3G network. The airport simply routes the relevant packets, triggering the wake feature. I don't see why BackToMyMac would work any differently.
When you did that via SSH, you had port forwarding set up? BackToMyMac's global bonjour is registered by macs communicating their connectedness to the mobileme servers, which is nice so that I don't need port forwarding. I suppose the airport router could be caching that as well... I'll just have to try.
I agree, that's why I always smash my dishes after meals.
Weird, I have an Airport, not the Extreme kind. Yet the iMac supports this capability.
Cool, though. =D

XMOS
The future of audio over ethernet. I could see Apple making moves to work on wired and wireless communication between Macs, iPhones/Touchs and an updated ATV (will they scrap the old one and make the Mac mini do this?)
James Foster: Smei conductor company. New reprogrammable chip. Ethernet AVB - Audio over CAT5 cable. Working with Apple about standards.
USB2 audio can be done on the same hardware.
In stores within next 3-6 months. (THis was posted back in January 2009). Was this the iFPGA? Probably mistaking the things, but seems ATV needs to get into the living room, and now Apple has the increase in Macs, and iPhones/Touches, with users having HDTVs, there's a way to bridge the digital A/V divides.

The MobileMe preferences pane has an answer to my question too...
That's pretty cool. Also, I RTFM'd this page: http://support.apple.com/kb/HT3774 . It actually describes Back to My Mac waking.
I'm a little disappointed when looking at my Mac Pro's system profiler.
Apparently, this April 2007 8-core Mac Pro doesn't support Wake On Wireless, which is something I've been waiting for.
Of course my MacBook Pro and my girlfriend's MacBook both support it--the two computers that are always on the move and don't even need it!
Any way to change this? Swap out Airport cards between my MacBook Pro and Mac Pro?

As it's been stated before 6 times in the this thread, over a wired connection is nothing new. This brings the ability to wake a Mac over a WIRELESS connection which is new - outside of third-party apps.
