Ok, score one more for "just shut down the entire network for a bit and then power it up again".
I had been fighting with the remote app for a while and all indications said it should work: firewall open, bonjour running, etc.
My network isn't too complex:
[Cable Modem] -> [old Delleron running pfSense (router)] -> [Switch]
[Switch] goes to all my computers as well as a Netgear WG302 access point.
What I found was this:
1) If I would directly connect the iPod Touch to my MacBook via ad-hoc wifi, it worked (but who wants to do this?)
2) If I have the iPod Touch and the MacBook both on WiFi, the Device would not even show up in iTunes when I was supposed to enter the number.
3) If I have the MacBook connected via ethernet and iPod Touch on WiFi, I can enter the number, iTunes says I'm good to go, but the iPod would not be able to connect to the library. Once in a while, I would get the name of the library, but never anything beyond that.
I reset the whole network (modem, router, wifi, switch) just for the heck of it (honestly, i wasnt expecting a difference) and much to my surprise, it works now!
just my 2 cents
