Live realt ime video straming

hey!

i'm trying to help a friend improve his website. he wants to add real time video streaming. we have access to our own server - so there are no limitation on that side of things. He is after purchasing a high quality cannon camcorder and has it connected to his PC. how do we go aobut ading live / real time streaming video to the web site. Eg if i logged into the site in europe - i could view him in america? to some degree its video confrencing - although he does not intend using it for this purpose.

Thanks in advance for all your help.

Cheers
