Eep, this came out wrong!  Let me clarify:

Many intra-machine networks like SCSI, LPC, HyperTransport, QuickPath,
and I2C are specifically not designed to be robust in the face of malicious
actors on the network/bus.

I don't know, *and was wondering*, whether this is true of Infiniband.

Does that make more sense?
