| Hi -- I am getting weird results with my remote slime connection.
| I am running and SBCL 0.9.16 and swank from SLIME 2.0 on a remote
| linux box, and connecting with SLIME 2.0 on 
|   GNU Emacs from 2006-12-16.
| When I `slime-connect' I get this prompt:
| Protocol version mismatch. Continue anyway? (yes or no) 

What do you get from evaluating

swank::*swank-wire-protocol-version* on the remote lisp, and
slime-protocol-version on the local emacs?

If they are not the same, you need to upgrade on at least one end.  In
my experience, it works okay to upgrade swank in a running lisp image,
and to reload slime.el in a running emacs, and open a new connection.
