you can either use fuse and its python bindings - this is rather trivial
filesystem-wise, of course there are challenges in order to implement
encryption effectively and efficiently (this is what encfs or phonebook
do, but they are written in C)

Or implement encrypted  network block device in python - again, this
should not be _that_ hard.

Or implement either nfs or samba server with transparent encrypted
storage - this is what (again in C) cfs does. If you go the samba way,
it would be even cross-platform - but I have no idea how difficult it
would be to implement a samba server in python.

In all the cases, performance is going to be THE issue.
