Ok, here's a WAG.  Your problem stems from the fact that the Unix
permissions on that directory really are 0.  All of the access information
is stored in separate ACLs, which rsync does not copy.  Thus, it sets the
permissions on the remote copy to 0, and, obviously, is unable to write to
that directory afterwards.

You can run "chmod -R 775" on that directory, which should, if my WAG
above is correct, fix your rsync problem.
	Igor
P.S. Before you ask, I'm not aware of any way to make rsync copy the ACLs.
