  Then, why don't you improve it, if you really think GNU Mach sucks?
IMO, the Linux emulation is not so bad. Don't mistake me. The reason
why I say that is _not_ because I did some work on it, but because it
was (and is) a very practical solution. Even if GNU Mach would support
user space drivers, who could implement them? Note that neither Hurd
nor Mach is a vaporware. We should find a realistic solution.

  You are ignoring the fact that successful projects are based on Mach
2.5 but not Mach 3.0. AFAIK, there is no commercially successful
project which uses multiple servers on a microkernel, except for QNX.
