Subversion is written in C, with the test suite and other supporting bits
written in Python. That being said, the code is relatively well-documented,
and pretty straightforward for folks who have programming experience.

Feel free to scratch your own itches, but we're always looking for able and
interested developers. I assume you're subscribed to the dev@ list?

The only discussion about new backends that has happened so far is what type
of features and APIs it should support. Ideally, the correct abstraction
levels would be chosen such that users could plug $DB_OF_CHOICE or other
storage mechanisms into a more generic FS or repository layer. But all
those types of decisions are a long way off.
