Video server type thing

["Will Parkinson" <willl69@gmail.com>]

Hi,

I need to build a service on which i can host a customised video conferencing program on which i can view and talk to up to 20 people at once.  Im just wondering what would be the best programming language would be for this, whether it would be better to be internet based program or stand alone desktop style program and whether debian would be a good server to host and manage it all on?  Been programming for a while but have done nothing at all with streaming media or anything like that

Any info or opinions on this greatly appreciated

Cheers

Will
