I've just superficially read the paper.
AFAIU this scheduler requires a lot of changes to userland.
For example X Server must report "features" about connected processes to features collector device.

Then, I do not quite understand how features would be propagated to dependant processes.
For example if you listen music via process1 | process2 > /dev/audio
Features of process2 must be somehow propagated to process1

It will be quite messy stuff..  At least OpenBSD guys would not commit it:)
