I will comment on the proposal directly as well, but coordinated releases
would be a disaster.  Mahout, for one, should not have to wait for Hadoop to
have a release.  We are already unhappy that we only get two releases a year
and want to up that to four.

Much better is to have a directed acyclic dependency graph with coherent
versioning.  That allows projects to stay independent, but still express
version requirements.

Multi-project access sounds right.
