Great!

Latest news on the Xen front: I've managed to do a `git clone` using the mirage 
direct TCPIP stack (in unix) and the raw Git protocol (git://). 
That's still a bit cumbersome:
- on OSX, the mirage stack needs to have a DHCP lease before been able to do a 
TCP connection
- the TLS stack is not yet integrated into conduit (so I cannot really test the 
smart HTTP protocol with Github's https)
- and there a few bits and pieces which needs to be clean-up.

working on the full Irmin+Xen integration until the end of the week.
