Lower latency yet would be AC Hypertransport cabling (up to a meter at 
full speed apparently, and then it's just a question of backing off for 
longer runs).  The lowest latency Infiniband systems already use HTX:

Interconnects on a rack would be about a meter.    Voilà, what was once 
a cluster becomes a NUMA SMP by cross-box Hypertransport!
