[olug] semi-OT: webcam for linux with local device

[John Hobbs]

What kind of webcam?  I have some base code for a gspca device I was
playing with you might be able to use if it comes to that.  Are these
serving out to HTTP or something home-brew?

If it's home brew I could see:

HOME:  Get frame
HOME:  Encode/Compress
HOME:  UDP to server
SERV:  Forward frame to clients
CLIENT: Decompress
CLIENT: Display frame

You could go pull instead of push on the clients too I suppose, time
stamp your frames so the client knows if anything fresh is there.
