Hm, depending on what "passing data files to each other" means,
something like the Luwak OTP application (bundled with Riak 0.13 and
later) or using Riak directly as a client could eliminate the need to
store any single file in any single place: data replication is taken
care of for you.

IIRC, that's one of Ericsson's main (or at least original) uses for

The Riak Core application could also be a good fit.
