Question : Problem: Hardware/Software to rebroadcast live video feed

We would like to take a live feed that comes into our network and buffer and rebroadcast it to multiple users within our network.  If all the users tried to get the live feed straight from the internet it would overwhelm our T3 connection.  Is there anything out there to do this?

Answer : Problem: Hardware/Software to rebroadcast live video feed

Thanks for your comments.  We actually ended up using the built-in broadcast feature of our Mac server.  It ended up being incredibly easy and required no additional hardware or software.  It's incredible, since the Mac server that we have is 5 years old.
