I've spent some time trying to port plan9port (aka Plan 9 from User Space) to the #Hurd yesterday. It's not quite working yet, but many subprojects already build, and at least mk works.
The really exciting part of course would be to switch the custom filesystems back from 9P over a Unix socket to real Hurd translators.
Here's another pretty screenshot for you'all
