Video Conferencing On Linux

I have normally had a bad experience with multimedia related software till today. An expensive IBM PC camera has not been working for quite a while, so I had banished it to my family’s Windows XP machine. But I needed one to play with for my own FC3 linux box. My hardware dealer at first insisted that I try out a damn cheap Chinese cam costing Rs. 950. The package was as cheap as it could be made, but the demo that he showed me was impressive.
