"Always On" Impromptu Video Conferencing Solution?

TristanBrotherton asks: "We have several geographically disperse offices all over the world. I thought it would be cool to make virtual windows in each office, linking a display panel with a mic and camera to the same set up in each other office. You could place these systems in public areas and in meeting rooms which would allow impromptu video conferencing, and 'hey bob nice shirt!' taunts to improve communication between our staff. I know you can get IP cameras, but I am looking for a simple all in one solution that can auto-connect, negotiate the best bit-rate, and remain real-time. Cisco charge tons of money for this stuff, but surely there must be a way to make a reliable system myself. Cringely thinks this might be built into apples iTv. Rather than wait on that, I am asking Slashdot what they would use to build such a real-time conferencing system, has anyone else attempted a project like this?"

We have several geographically dispersed offices all over the world.

Are they also internationally panglobal? To save on videoconferencing call charges, try removing the redundancy from your style.
