Almost everything you need is done for you: set up a keyserver.
Given what you're describing, it sounds like a LDAP keyserver is the
way to go.  GPG talks to it natively, and you can do any sort of
queries you like.  For example, an email search can be as simple as:
(pgpUserID=*the-address at i.am.looking.for*)
