Pipe dream: MultiVersion Concurrency Control, like PostgreSQL implements it, but for packages instead of regular tuples.  Hrmph, PostgreSQL BLOB/bytea support is good enough to serve packages out of, now.....  A reader will always get consistent data in an MVCC scheme.

Yeah, I know, I should know better.  But I was told that same thing years ago when I first started advocating delta rpms.  Now we (well, not CentOS, but upstream Fedora at least) have presto, and, yeah, it works great.
