It means something to me. Kevin
I am far from needing one of these yet but I am interested in them. I think that clearing up who does the transcoding would help some people. I wonder if someone will use this for large scale network needs. Image Stream is just down the Highway from me and I know that they are using ~1 gigahertz processors on their T3 routing systems with multiple NICs. What would be a real example of use. EG: A Tyan Transport TX46 and this card could handle what ever you could put on it. What is the realistic low end of system that could support this card.
