So, kind of stupidly, told someone I could add a live streaming video from their webcam to their site as I thought I'd read a simple tutorial on it a while ago

Thing is I now realize how stupid that probably is, and looking into it, seems the only way to do it is with flash media server, is that correct?

If so, do you know if it's available on Mac? I haven't read anything saying it's not, but I can only find a Windows and Linux free trial on the Adobe site

Any help would be really appreciated
