I'm curious if anybody can give any insight as to what kind of performance to expect from authentication binds ? How many POP3s/second should we expect from it ?

Try yourself with imaptest (http://imapwiki.org/ImapTest):

imaptest - select=0 clients=<try different values>

It'll authenticate the same user, but as long as you don't enable auth cache it'll still do the LDAP lookups and you can get a pretty good idea of the performance.

My guess is that the performance bottleneck won't be authentication binds, as long as the latency between Dovecot and LDAP server is small.
