I can write ldap_queue, the last ldap plugin I need, without any weird u_domain_tld uid's for cyrus. That means plugins can be fairly generic, the base and filters easy to adapt to other situations.
http://perlq.org/tinyldap/ about deb cyrus21, unpatched, can do [EMAIL PROTECTED]
If I can just get dspam going, lmtp will work from dspam to cyrus imap, now that cyrus won't need weird uid's. Looking at Net::LMTP to avoid the need to exec dspamc to do lmtp to dspamd on the front end.
