There are certainly larger cards than that..
Ive seen systems with 16 ports..
If you had something like a Digiboard 8i/8e card, performance
would be pretty good because the serial handling is actually
on the Card, NOT the CPU.. It has it's own processor and memory.
BUT.. you would have to write a driver for it, but looking at the
very good docos that came with the card, would not be hard for
someone who is good at Kernel hacking..
