Yes, do you expect the version directory to change as well?  Since the
application ID would have both pieces of information it seems like
passing both would make sense, and then return an error if that isn't
the correct version.  It seems like there might be a read-only version
and then an upgraded version as well, where even the base directory
would change.

Long term (not v1) I think it'd make sense to have it be a library call
or something simple to document so that we don't have to start another
process.  I'm getting a little concerned about delaying application
startup.
