Given discussions regarding CPU requirements for a single machine node, thought you might like to know I saw a pre-production dual P4 (1.7GHz Foster) from Dell today: 64 & 32 bit PCI buses, built-in 1394, onboard fast Ethernet. The real news is that they expect to start shipping these in May with a reasonable starting configuration under $4K. Needless to say, 4 cameras and all those video streams are not going to be an issue. We also had discussions with Viewcast/Osprey about getting P4-optimized drivers for their capture cards and we're following up separately with their development team next week. It would still be nice to get all of this running on a single proc P4 to keep the cost down even further. Todd Needham Manager, Research Programs Group Microsoft Research http://research.microsoft.com
