I've never been able to get cygwin/ssh/rsync working reliably
for WinXX.

I see the same thing: a few files transfer but then it hangs.
I believe it is some bug in cygwin sockets that ssh exposes.
There were rumors on the rsync mail list that the latest
cygwin1.dll fixes this, but that is unconfirmed.

Rsyncd/cygwin is reliable.  But then the traffic is not encrypted.

Without an ssh tunnel (either rsync over ssh, or rsyncd over an ssh tunnel)
I don't know how to do this.
