A day and a half of hacking at PyCon, and bam!  r10358 includes a whole
bunch of changes, including separating the SFTP protocol implementation
from the filesystem interface.  It now looks for an adapter from the
avatar (the default server uses UnixConchUser) to ISFTPServer.  The old
filesystem implementation now lives in SFTPServerForUnixConchUser, an
adapter from UnixConchUser to ISFTPServer.  You'd just make your own
type of avatar, and a seperate backend, and register an adapter from the
avatar to the ISFTPServer interface.
