What would you cache?

slapd already has some of it's own in-memory caching.

My (and many other people's) experience has been that the bottleneck in 
the ISPMan web control panels has been Perl - it's parsing/compiling 
every perl package on every single request which is pretty wasteful. The 
actual LDAP queries are pretty quick. For example, PAM and Postfix are 
super fast at looking up things in LDAP.

That said, memcached looks really nifty; but it could unnecessarily 
complicate things when their's other solutions available.
