Hi Ceki,
Different Scala versions are binary incompatible and I don't believe that will change in the near future, even if Martin has said that once. IMHO 2.8.1 will not be binary compatible with 2.8.0. And 2.8.2 won't be with 2.8.1 nor with 2.8.0. And of course neither of these is compatible with 2.7.x. If you are interested in the reasons, you will find numerous resources on the web, e.g. [1] or [2]. Maybe starting from 2.9 EPFL will manage to solve that issue.
I hope they do. [cut]
Akka has not yet been released (only milestones) and therefore they can target only one Scala version. But they already do it the style I described, i.e. they are ready for multiple versions. Lift already does builds against 2.7.7 and 2.8.0. And there will be others.
For something as widespread as SLF4J there in NO WAY not supporting 2.7.7 plus 2.8.0 plus 2.8.x. It just must be cross-built.
Indeed.
So your (d) is not an option, but as I already mentioned I hope to find a Maven based solution.
and you have... Nicely done.

So it seems that traits are the culprit. -- Ceki
