[Pc_Support] Streaming Video over LAN to Browser.

[BBBB]

I am looking for suggestions for streaming video on an office LAN. 
This is for a studio that produces TV commercials. The idea would 
be that the client/agency/producers/etc, would be able to see what is 
going on in the studio without being in direct sight of a video monitor. 
(they are usually in front of a computer screen)
I have VLC streaming but I haven't been able to get it to open a 
Firefox plugin. It will only open with the VLC player. I am still
working on VLC and may get it working. Everyone will have a 
browser on their laptop or desktop. (About 50/50 Mac and Windows.)
I will have a composite video signal for input. 

If anyone has had good or bad experience with this type of setup, I 
would really like to get your input and suggestions. 

Thanks,
Bradley
