I think sshv2 is a Great Leap Forward (thank you!), but I'm not quite ready for the upheaval of nfactoum and a non-standard lib9p. I've attempted a minimal conservative addition to standard factotum to make it useable with ssh2, and that seems to work for me. If anyone else wants to try it, just replace /sys/src/cmd/auth/factotum/rsa.c with /n/sources/contrib/miller/factotum/rsa.c and rebuild.
