If the answer to #6 is "Yes", it would introduce a nice IPC mechanism that I could see being useful in GUI, simulation, and automated test software. Of course, the answer to #6 depends on #s 3 and 4. Also, certain of these would have security implications as well.
I suppose I ought to get a recent kernel source distro, apply the proposed patches, then search out the man page, look at the implementation, and see if I can find any flaws in the API that should be addressed.
