[Twisted-Python] Conch and Rsync

I have an application that runs on Windows, and I want to be able to sync files back and forth from/to a unix server. The unix server has sshd and rsync. Can I use twisted/conch on the Windows box to call rsync (over ssh) on the unix server to push/pull files to/from the Windows box ??? Do I need something like rsync.py in my Windows app ? If so, would it be an rsync client and/or server ? Thanks for any info and thoughts. Brendan.
