Aha! I thought the slave repository could only used for reading and 
commits would just fail instead of being passed through.

We trigger an update on a sandbox from the server, so we'll have to be 
carefull about timing if we were to do the same on a sandbox connected 
to the slave server.

What happens if a user updates a file from the slave server exactly at the 

same time the file is being updated by rsync? Is this handled? 
While unlickely for regular sourcefiles I can see it happen for large 
binary 
files.

Or creative use of rsync and the commit support files to just sync the 
files
that have been committed. After all that can be determined from %s.
