Thanks for the suggestion. I noticed it has a scheduling feature which is nice and what I've been looking for. I have several other questions in relation to this:
What kind of hardware would I need for this, and what type of internet connection? Would a normal pc or a netbook with an attached higher quality webcam (thinking of going with a higher quality Logitech) be enough? What about bandwidth usage? Wouldn't I need a really fast upload connection if I'm planning on using a direct stream? Cable modem? FIOS? Or is there some service which allows you to stream to them and they relay to your site (similar to Justin.tv or Stream.tv, though I'd prefer not to deal with them in particular)?
I shall try and answer all of these to the best i can, but i can tell you now i'm no possessional on this!
I have done this a couple of times now, once just through my built in camera, the quality of the camera, is crap, but when i saw it on the internet i didn't think it was that bad. I have also used a high quality camera (cost me around £50) and the quality was fantastic, did lag at times, but you get that no matter where you go.
So, i would recommend you use an attached camera, but built in ones do work fine.
I'm affraid i don't know the full answer to how much bandwith it was using... HOWEVER, i can tell you that i was uploading it, while on sufering the web, and the effect wasn't that bad. I have also ran it through 3G on my phone, connected to my laptop, and it was OKAY but i couldn't load anything else.
I have allways used a wireless.
Sorry, but i have no experience on the other services, i did try using steam.tv but i got fed up with it.
May i also point out that the audio on it isn't very good.
