I was (somewhat) following a dicussion about high speed communications
handled over the PCI bus, and there's a company that makes T1/T3-level
serial cards for PC's, and from what they were saying, there's no way to
reach even a full T3 worth of bandwidth on a PCI bus,
PCI is 33mhz at 32bits = about a gigabit per second. Fast PCI is
66mhz, and a fast 64bit PCI standard is coming, which yields 4Gbps
across the bus. Now, admittedly, you can't get that fully -- but if
you claim you can't get a mere 45mbps across the bus per second you
are doing something desperately wrong and stupid, like making the main
CPU deal with *way* too much of the work. Of course, most serial
communications companies ARE doing things desperately wrong and
stupid, but that another story...

In any case, I'd be pretty
