Well said, Andy.  With today's high-intensity I/O cards, the PCI bus has
become a notorious bottleneck for sever implementations, necessitating multiple
(split) bus approaches to compensate, and whole new paradigms like InfiniBand
to avoid bus issues entirely.  Bus capacity is often overlooked in server
planning, and can be a (mysterious) show-stopper.
