[Dovecot] dbox with non-dovecot LDA

Aside from the code is there any documentation on using dbox with a non-Dovecot LDA?

We have our own MTA and currently use Dovecot with Maildir only for message retrieval and just have our MTA write the message files to our own directory structure (Dovecot per user mailbox locations stored in mysql) but I am interested in looking at moving to dbox if it is better for performance and other things like static filenames. One thing we'd like to do is not use the Dovecot LDA so as to control the entire inbound email delivery process all the way to verifying the actual message is 100% written to disk. Certainly we can use the Dovecot LDA if it came to it but we'd like to retain control over this entire process if possible.
