Can we wait until we bring the common/of stuff back from the tmp
branch? It'll make the changes to the openib BTL significantly
easier to merge.
I don't know Torsten's/Gleb's timeframe for moving everything to

Yes, I very much care about backward compatibility of the openib name
and MCA parameters... This is, as I see it, the biggest issue with
changing the name. Stuff like this has to work:
mpirun --mca btl openib,self ...
mpirun --mca btl_openib_foo 32 ...
