The code of UVM is complicated enough that it seems easier to start
with an OSkit-based pager first. It won't be of very good quality,
but we could already pinpoint the external IDL interfaces (as long
as we take UVM into account). Maybe again, someone is willing to
dig into UVM code anyway... ;-)

The VK/L4 is not intended to be a _monolithic_ kernel in any way.
VK itself _may_ run on a monolithic kernel, e.g. in VK/{Linux,BSD,...},
but this is only a borderline situation. VK is intended to be a virtual
_microkernel_ that is somewhat situated between L4 and Mach and that
provides services upon which a full blown OS personality can be build.

In the VK/L4 case, VK seems to evolve into some kind of mini multitask
kernel consisting of L4, pager, driver(s) and some communication channels
(which currently will be only IDL abstractions, maybe a nameserver...).
Call it "multi server virtual kernel" if you want (somewhat like a
Hurd-in-the-Kernel, which is rather amusing if you reflect about it).

There is nothing monolithic about it.
