Currently the best way to do this is part of the long-haul replication
package in Riak EnterpriseDS.  It looks like you also filled out a
contact form on the Basho site, so we'll be in touch with you off-list
to help you with that.

The in-cluster distribution model and the long-haul replication are
very differently optimized in terms of network usage.  Configuring a
single cluster over WAN is not what you want.

Either I or someone else at Basho will be in touch later today to
discuss your needs.
