Hi Thomas,

This would be good.

Yes, definitely.  I only listed those *I* need/use at the moment ;-).
LDAP would potentially be useful for me as well (although I try to
minimise network dependencies as much as possible) and other systems
will of course be useful to others.

Ummm yes, having servers for ecomplete and mail abbrevs would make
sense.

As a first step towards using eudc-expand-try-all as the basis for
completion, I tried changing message-completion-alist (which is what
message-tab uses) to invoke eudc-expand-try-all but this didn't work.
Not sure why.  Will explore and report back as this might be the easiest
approach.
