Use the "--no-transport-auth" option on the server:

mtn serve --bind $HOME/mtnsock --no-transport-auth

(Hrm - I guess the other option would be to override the standard lua  
hook to use transport auth with ssh+ux connections...)

But, if I leave that option off then I don't get a hang, I get an  
error like this:

% mtn pull
mtn: doing anonymous pull; use -kKEYNAME if you need authentication
mtn: connecting to ssh+ux://localhost/Users/willu/mtnsock
mtn: finding items to synchronize:
mtn: error: protocol error while processing peer ssh+ux://localhost/ 
Users/willu/mtnsock: 'protocol version mismatch: wanted '6' got '237'
mtn: error: the remote side has a newer, incompatible version of  
monotone'

and the '237' changes each time.  The auth request is being  
misinterpreted as the version information.
