Python-based file synchronizer (like Unison)?

Well, I have something for you called PySynchro.  I wrote a simple 
client/server application
entriely in Python. Personally I use it for synchronize source codes 
between various computers.
It uses secure connections, authentication (OTP variant). It is plaform 
independent (I tried it
on FreeBSD, Linux and Windows. I don't know how it works on Macs.) It is 
not a hyperspeed
syncronizer (although it transfers the files in compressed chunks).  It 
requires some popular libraries
to be  present but the main point was independency. It does not require 
any external programs /
database servers etc. On the client side, there is a class representing 
the client interface
and I have a wxPython UI that uses this interface to synchronize files.

There are some problems, though. I would like to implement persistent 
file locking and auto-locking
but it is not written yet.. It would be also possible to store 
'versions' but it is done yet. From other
aspects, the UI interface is similar to Borland's TeamSource (with some 
major differences in the
background). If you only want to compare and merge directories, you 
 will find some useful classes
inside.

The code is fairly well documented (with epydoc) but the whole idea of 
the program is not.
Let me know if you are interested. I have been using it for months 
without problems but you can be
the first beta tester. :-)
