Yes, there are some ways to do this. Although you would most likely want Dovecot proxy without director feature enabled.

Since I'll most likely be contracting with your company to help with this, I'll wait and see what you say once we're ready to roll this out - and maybe you'll be willing to give us a deal on the implementation and/or support costs if we're willing to serve as guinea pigs. ;)

Possibly. :)
