Sending binaries over relations

[John Meinel]

It does feel like a good fit for resources, with the one caveat that he
wants to maintain a lock-step version of the resource across services.
There is slightly more work with the current designs for resources, in that
each charm will think about its version of the resource independently. But
we will have the fingerprint information to allow for users to compare and
be confident that both services are using the same resource.
