I haven't followed the conversation closely, hopefully all of this was not
discussed yet ;) The solution you are aluding to sounds a lot like the
git-version-gen script which is used in several projects, see
http://stuff.mit.edu/afs/athena/astaff/project/opssrc/cups/autoconf-2.65/build-aux/git-version-gen
for example.
This is the solution Eric mentioned at the beginning of this thread
https://www.redhat.com/archives/virt-tools-list/2013-April/msg00106.html

The way the versioning is done is:
- if there's a 'vXXXX' tag pointing at the current HEAD, then version is
  XXX
- else version is XXXX.z-hash where XXXX is the most recent tag in the
  current branch, z is the number of commits made since that tag, and
  hash is a short hash for HEAD

This gives you a version number that always increases, even for snapshots
from git.
