> PCI is very delay-tolerant

That fascinates me. Intel deserves a lot of credit for PCI. They built in future proofing for use cases that wouldn't emerge for years, when their bread and butter was PC processors and peripheral PC chips, and they could have done far less. The platform independence and general openness (PCI-SIG) are also notable for something that came from 1990 Intel.
