That's the "mach".
GNU Mach is really Mach + our tweaks.

Yes. The Mach device interface is in <device/...>. Unfortunately, the
terminal interface is not so good and needs a redesign.

A loader does not enhance the design conceptionally at all, so it is not
interesting. Some people think hardware drivers in user space are appealing,
other disagree. Only time will see.
Mach is a *microkernel* through and through! Quite different from a
monolithical kernel like linux.
Anyway, you should not concentrate on Mach too much. The Hurd is mostly
independent from Mach, and could be ported to other microkernels.
