Nice app :-)
I haven't figured out to connect to a second computer's camera. I've got iCamSource running on two machines (macs on the same LAN, with unique usernames). I can connect to both, but only one at a time (if I use iCam on the phone to Login to the other machine, that's machine's video replaces the first machine's video stream, rather than showing up in its own video window). I'd really like to have feeds from both machines at the same time.
I'm sure that it's such a simple function that I've totally missed how to implement it (I used to design UIs, so I understand the frustration of the developer with dumb@ss users, apologies!). May I suggest a way to reorder which video stream appears in which window? (I only have two machines, but I'm betting that you'll get users running more than 4, and it'd be good to have a way to choose which window drops an unneeded connection for a new one).
By the way, I too am having no luck connecting outside of my LAN, hoping for a fix with 1.0.2.
edit: managed to get it to connect via EDGE, started working when I restarted my router :-)
