I'm glad you're interested. For the benefit of l4-hurd readers, let
me reiterate that the linked-to code does not do anything remotely
useful, it's there for informational purposes only. If/when I get
something that I think is "portable" to other people's i386-Linux
machines, I will announce a 0.1.

I definitely intend to hack with it. One potential problem for using
my work (assuming it becomes usable) in an effort to port the Hurd to
L4 is that I am prefering Linux dependency to x86 dependency where I
have such a choice. However, I aim to keep both kinds to a minimum
without needing to recompile userland Hurd code.
