If both source and destination are remote, rsync complains:

The source and destination cannot both be remote. rsync error: syntax or usage error (code 1) at main.c(1156) [Receiver=3.0.7]

Is there a insurmountable technical obstacle to making rsync do this? Or it's simply a case of it's-not-yet-implemented? It seems relatively easy to create a local buffer in memory that mediates the transfer between two remotes, holding both hashes and data.

Conversely, is there other (unix) software that implements this functionality?
