It's a more complete multi-master solution. The result is even better:
full high availability access with multiple Subversion servers,
synchronized write access to the core repository, and you don't have
to write the potentially fragile and split-brain prone hooks yourself.

I am not sure how this is relevant to Aaron's question, or if you just want to rationalize past purchase decisions. Using a paid vendor is a choice one can make, so is to the exchange for enterprise pricing.

I actually never bought their services. Their multi-master setup
wasn't available to me fiscally when I started supporting Subversion,
and I'm not currently running high availability Subversion
repositories. It just seems to solve a lot of the underlying issues
people try to address by doing master/slave Subversion setups, in a
more effective fashion.

We've only so many hours in our workday: making configurations from
scratch can be very interesting and exciting, and I'm glad yours works
out so well for you. But it can be fragile and risky and takes some
real thought. So that's why I ask "what is your time worth?"
