Do you have any specifics on resolution, format, etc that is preferred for this task?

I could do:
*screencasts (bleh)
*use my sub-"dslr" - video is 640x480 or 320x240 in .avi container (motion JPEG). It has good optics though.
*cameraphone 176x144 mp4 or 3gp, heh.
*I'd list the n810's camera but it is miserable.
*I also have a pretty decent webcam I guess.

The only thing that strikes my fancy at the moment is alternative networking though.
