Mongo for saga persistence

How about using mongo for saga persistence?

I started using the file system event store since it gives me speed
and simplicity. It felt good to be able to remove all database related
dependencies from my pom.xml. Then the sagas hit me...

I'm using mongo for the view store anyway so I already have to support
that technology. Not having to choose a JPA compatible datastore and
support it would be very nice.

Who built the mongo event store? I guess there's some reuse possible
from that code.

I can have a look at it, will try to find some time.
