Well, RoCE isn't a wonderful name, is it?

FWIW, this is a pretty reasonable paper:

How about CXL-over-UltraEthernet?

Also, I'm interested to hear feedback about NV's recent moves in the direction
of collective offload.  The UE paper above doesn't really address that (only one
real mention of collectives, and sneering at Verbs in a few places...)
