Question regarding webcam streaming and bandwidth

Hi,
A friend of mine wants to set up a 24/7 webcam at his venue that will broadcast a feed over his 1.5mbps T1 connection to a website (located in a remote server elsewhere). Users would go on the website which is on its own server, and watch the feed from the site. This would be a basic media player embedded on a webpage which uses the streaming computer's IP as the source/address for the video.
Now, my question is(if I explained the above portion clearly), if multiple users connect to view the stream, which internet connection is being stressed, the webserver's or the camera server's?
Regards,
David Browne
