It would certainly be possible, provided you have sufficient network
bandwidth and high-definition cameras (indeed, we have an NSF-funded
project to work towards this which will be starting later this year).
We've run tests over Internet2, with gigabit Ethernet LANs, and it works
well (although this only gives capacity for a unicast stream, and needs
careful monitoring from the network operations staff). Our hosts are Dell
PowerEdge 2500 servers (dual 1.2GHz PIII, dual 64bit PCI slots) with HDTV
camera and video capture card. The host cost approx. $100k at the time we
bought it (this included $80k for the camera, which should be much cheaper
You can find an early version of our software, plus more details of the
hardware needed, at http://www.csperkins.org/hdtv/download.html. We plan
to make more advanced versions of the software available in future.....
