Next thing nothing, have a look for the Perl Filesystem (my bookmark is
ancient and broken but it got a mention recently in the Hurd mailing list
digest). This basically allows you to write a filesystem kernel module in
perl, I imagine it could be adapted for other type of module too.
I think they wanted to create a new network fs and they figures that
network slowness would esaily outweigh perl's slowness,
