I recently put in a 7i25 card because of latency issues. This make a pretty rock solid system. I don't see the big difference between buffering using a pci card, vs a usb device. Mesa has a high speed usb breakout that would probably work?? I think it uses the high speed ftdi chip? I think perhaps the real reason there isn't much support for this remote controller idea, and not necessarily a bad one, is that people have their hands full, and don't feel like doing it currently.
