document/automate use of monkeysphere with lsh
"lsh":http://www.lysator.liu.se/~nisse/lsh/ is a GNU implementation of the SSH protocol.
we should sort out how to use monkeysphere in conjunction with lsh.
most problematically, lsh appears to use yet another key file format, so we probably need to help the monkeysphere figure out how to deal with it.
