Bind with an LDAP Backend

I am thinking of doing some research here. Anyone started this so I am not re-inventing the wheel?

I have a large dns implementation consisting of 69 domains along with delegated subdomains.
My brainstorm:
I would like to build a pair of openldap servers with a special schema for dns record type attributes. A. MX,CNAME,SRV,RP,MB,PTR etc.. Assign OU's in place of domains. Provide write permissions to authenticated binds. Then Output via ldif to an include file to a domain zone listed in named.conf, This would allow the ldap user to write to an include file and not modify the ns and soa records. Have another process rndc <zonename> and away we go. I would love to work with somebody on this if your interested pm me. I would like to document it and publish it on the web or send it to ISC, who knows maybe Bind 10 will do zone transfers from slurpd and slapd.
It has to be possible, as I got the idea from Microsoft Active Directory's integrated Zones being stored in AD.<ldap>

Cheers
