development for fully supporting multi-master-replication of dbmail data with multiple nodes

I am running dbmail 3.0.2 in a MySQL multi-master (2) replication 
configuration.

I understand that this will work fine as long as the IMAP unique_id does 
not become invalid due to the same user connecting to both nodes 
concurrently or because of a failure in the replication and the user 
connecting to both nodes during the fault.

I understand that a proposed resolution to these issues is discussed here:

http://www.dbmail.org/dokuwiki/doku.php/unique_id_guid

Can someone confirm that this *is* the current status of full support 
for complete multi-head database replication?  Namely, "that this is the 
last thing holding DBMail back from a complete failover system using 
MySQL replication"?  (Quoted from the URL'ed page.)

I am willing to pay for this development to be done... if someone here 
would like to do it.  Any takers?  Let me know how much you want for the 
work.  Otherwise, I am willing to do the development, myself, pointers 
appreciated.

(I recognize that 3.0.2 isn't the latest release.  It is just the latest 
one in Fedora which I installed via 'yum'.  I am willing to update, of 
course.)

Thanks,

Lee.
