Chaining event stores

I have a very disconnected distributed environment with many sources of truth , is there anyway to chain event stores via a pub sub mechanism ? I can build this manually eg via VS-Eventing but is there something built in ?

Im particularly interested in streams having the same id on each store,

Regards,

Ben,

How many are we discussing? And is it all streams? If so the new
replication model is what you want. If not you want a little program
on the outside, I can provide you most of the skeleton of such a
program.

Cheers,

Greg
