I know what they are, I implemented them in 1999 ;-)
The short version is:
a) No IMAP server does it yet
b) There is no reason why a IMAP server shouldn't do it
c) The tricky part is specifying the query criteria. Maybe using ugly encoded folder names?
d) You would have to hack a IMAP server to do it
e) You would probably have to reimplement the message storage to make it remotely efficient
f) Exchange uses around 800MB of RAM to provide this sort of functionality for 30 users ;-)

LDAP, please, not IMAP!

KConfig-over-LDAP was discussed once, and, I think, declared "a neat idea".
