MS just announced a parital list of features for Exchange 2007/sp1 and one of them will
be huge if done right - SCR or Standby Continuous Replication. The big killer for us with CCR
was the requirement of both boxes to be on the same subnet. We also did not really want to
have to run a cluster to get replication to a remote data center, instead we were looking to replicate remotely via stand alone boxes. This greatly reduces the complexity (no clustering)
while giving us the data protection necessary in today's environment.
Please, please MS, make SCR work and make it work without stretched subnets.
