That's why I thought, but if so, the following part loses me:

Nathan, you won't be able to use Infiniband between Ney Work City and 
San Jose, CA, anyway, right? Even without considering IB cables' length 
limitation, and unless you can use some kind of dedicated, 
special-purpose link between your sites, the public Internet is not 
really able to provide bandwidth nor latencies compatible with 
Infiniband standards.

IP is probably your best bet, here, and DRBD would probably be an 
appropriate candidate for this kind of job. Although, you probably 
don't want your synchronization data unencrypted over the public pipes, 
and you may need an extra VPN-ish layer to ensure data confidentiality.
