It is an abuse yes,
but the great thing about it is we _know_ it works...
so no surprises...

(if it aint broken...)

Well, the old simple logic works...

lets say we "abuse" the release tag, for example changing "mga" to "mgt"
then if the user enables "tainted" (meaning he/she wants the rpms) urpmi 
will automatically get the "mgt" ones, no questions asked...

simple, and effective.

and since the rebuild should be automatically on our bs, the versions
will stay in sync.

I'd say go for the setup that we know works for Mageia 1, and re-evalute 
the issue after...
