Yeah, I've deliberately written the PulpDist plugins to make as few 
assumptions as possible about the content - they're intended to be a 
"lowest common denominator" kind of deal while still being more 
bandwidth friendly than transferring whole files around all the time.

The closest they get to custom metadata are the PROTECTED files used at 
downstream sites to tell the plugins to leave particular directories 
alone, as well as the STATUS files used at the top level of snapshot 
trees to say when a directory is ready for synchronisation (or has 
already been synchronised).

Heh, I can hardly complain too much if anyone starts using my unfinished 
code when I've been doing the exact same thing to the Pulp team with 
respect to their v2 REST and plugin APIs. In truth, I don't actually 
mind so long as people have a clear understanding that they'll be 
building on a still unstable foundation :)

FWIW, aside from the updates needed to use the new Pulp APIs properly, 
and possibly switching the command line client over to the new 
pulp-admin plugin architecture, I don't anticipate any more drastic 
changes like last month's complete redesign of the approach to PulpDist 
site configuration.

Cheers,
Nick.
