I'm not sure I follow - maybe I'm being thick, but how do the *edge*
headers make a difference to the server version that has been

If you are talking about the fact you need to run a non-released
version of the server to get the right version of the common libraries
for the client to work, and you are using the wire protocol, then all
you need to do is to have a different load path for the client and the
server. There are few easy ways to do this:

1) Run the client on a different machine :-)
2) Run the client and server as different OS users, and make sure the
client has the *edge* version of the common libraries in it's load
3) With the same user, do the same as 2, but write your scripts to set
the load path appropriately.

This does however highlight some things we need to think about when we
release the client - Edwin started a thread about splitting out the
common libraries into a separate package (in fact, he commented on
this again today). I think one of the problems is the way that we
target Debian to a certain extent, but I'm not quite sure how it is
supposed to look yet.
