Is there any problems running clients on Sid, but having your servers
running stable? An example which springs to mind would be postgreSQL
where the Sarge version is 7.x and Sid's client is
postgresql-client-8.1.

I am guessing that you can't use the postgresql-client-8.1, i.e. psql,
but would have to use ODBC or something similar.

Do you have to worry about which versions of software your users are
installing to access your servers, or, do you control all of that.

AIUI, its normally just the protocol version, e.g. HTTP for web servers
etc, that you have to worry about but is it always that simple for all 
your server apps.

Can you point me to the path of enlightenment?
Or even a good book. :-)

Don't forget to check that your /etc/apt/sources.lst entries point to 
etch and not testing, otherwise you may end up with a broken system once
etch goes stable.
