>From purely a spectator's perspective, I believe that if one needs to add considerable complexity to Plan 9 in the form of user-based kernel resource management, one may as well look carefully at the option of adding self-virtualisation to the Plan 9 kernel and manage resources in the virtualisation layer. Plan 9 has provided a wide range of sophisticated, yet simple techniques to solve a wide range of computer/system problems, but I'm of the opinion that it missed virtualisation as one of these techniques. I may be dreaming, but I've long been of the opinion that Plan 9 itself makes a great platfrom on which to construct virtualisation. ++L
