I have two offices where I would like to promote working together by having a constant live feed into the other office. I'd like to set up two 40 inch TVs with cameras on top. The idea being they will be a "window in the other office and promote interactions between staff without having to physically go to the other office.
A persistent skype connection would be the easiest, but in my neck of the woods our internet connection is not that fast so I'd rather the service work only on our internal LAN and have no effect on your internet connections.
I can only find solutions that connect over an internet connection. Any ideas for LAN based video conferencing that i could throw on to a TV somehow?
