I see two solutions for you here:
1. Write a Rails application that uses the mogilefs-client stuff to
save/retrieve files as users create/request them (as MogileFS was
intended to be used).
2. Use the FUSE mogilefs client to mount it as a filesystem for your
entire rails project, and have mongrel serve up files as if they were
static directly from public/.
Knowing the state of the FUSE client the last time I looked at it, I
would probably go with the former solution rather than the latter.
There are other
relational-master-metadata-distributed-replicated-datastore GRID style
filesystems out there somewhat similar to MogileFS (like GFarm,
CleverSafe, or even Hadoop), but MogileFS is probably one of your better
bets when it comes to simplicity and a proven track record for Rails
development/integration at the moment (with mogilefs-client).
I suppose, in theory, you could modify mongrel to use mogilefs as a
filesystem abstraction layer, but I really don't see the need for that
Smaller. Simpler. Faster.
