Well, the first problem i can see is that 640x480 30fps color tv is going to need more than two and a half times the full bandwidth of a 100mbps ethernet network. Remember to divide by 8 when dealing in serial interfaces, that's a 12.5 megabyte/second interface. Its asynchronous and shared, too. I've never personally seen an ethernet controller approach 12 megabytes per second, let alone 12.5. Closest I've seen was 11.4. (This is using netperf, nothing but a crossover cable between identical nics in identical PIII-550 machines) So essentially you need 3x the generally available bandwidth of fast ethernet. So, you'd probably want to use some sort of compression. And then it's just run of the mill media streaming, there are a lot of apps for that. A number of them are listed on freshmeat. - Eric
