Having created two divergent branches on my own (working on two different 
virtual machines), sometimes it works right, sometimes it doesn't.  I've had the 
fewest failures with bzr.

   This is why you want a dvcs that uses its own patch format without any user 
control.  Fewer ways to screw up.

There are always merge problems.  The question to ask is "how hard is it to 
repair them".  Some systems have been horrible, others not so bad.  The other 
question to ask is "how hard is it to screw up a merge".  The answer for every 
single system I have used is "not very".

bzr supports a variety of modes of operation which are really nice.  Instead of 
giving you a garbled description of what they do, look at this document 
specifically chapters 3-6 http://doc.bazaar-vcs.org/bzr.dev/en/user-guide/index.html

I think the development model outlined in 6.3 (distributed with gatekeeper) 
would be most appropriate for this project.
