Can you elaborate a bit, both re. what you see as the difference between 
fault tolerance vs. HA, and re. speed?
Currently, I'm running a collection of services on a single VM, with 
DRBD/heartbeat/pacemaker failover to a 2nd node.  Failover takes a LONG 
time.  Looks to me like Remus should provide instant failover.
Thanks,
