One of my friends has written a program that can be installed on an SGI and hooked up to inetd that'll brab an image and return it whenever a connection's opened to it. Combine this with the proxy module on apache and some java script, and you have a nice webcam system. My website (http://www.thecommune.org.uk/~lisa
- BEWARE, may be work unfriendly!) has one on the front page.
I might see if I can get them to release it.
