I'm more interested in the "distributed" part of the story. Version control can be fitted into any database with a bit of hacking, but a distributed ACID database where you can commit to any node and merge with any other node sounds like a really interesting concept.

Especially when combined with the fact that it is extremely difficult to forge git history without getting noticed, people could use something like git as a reliable, scalable, and censorship-resistant platform for data sharing and storage.
