If I may suggest? You're re-inventing yet another in a whole set of
wheels for high availability support. Why not just buy the whole Land
Rover to start with, talk to our friends and colleagues over at
www.wandisco.com, and check out their commercial support for
multi-master setups for Subversion? With all the work they've done to
provide genuine multi-master support, I'm sure they've devoted good
support to shared authentication. In fact, I'm sure the shared
authentication is built into numerous Apache modules such as mirrored
flat text file account management distrikbuted through cfengine or
chef, LDAP with Kerberos, NIS, or a dozen other services.
