The gobsd.com page doesn't seem to be available anymore / at the moment. Its content, however, is available here: <URL:http://lists.gnu.org/archive/html/bug-hurd/2006-04/msg00019.html>. The email (which was also sent to the author of that blog entry) didn't receive a reply so far.

The migration of GNU Mach VM to FreeBSD one is simply not possible, since we need memory objects to do some stuff on user-space.

We need a new design to the Virtual Memory system, and Mach based ones are not a good idea for microkernels. We could check some other systems, like L4, that put the VM on the user-space, or Spring Nucleus, that has something more similar to Mach VM. But, on any case, we need a redesign of that part.

GNU Mach's IPC / VM system could be worked on. It might be worthwile to have a look what other systems that are based on / influenced by Mach have done over the years, see <URL:http://gobsd.com/node/219> for one example.
