Ahem. Not to be pedantic, but the leases file already is a database. 
What you mean is store it in a RDBMS. The best way to fix this would be 
to have an abstract storage API that could have dynamically loaded 
modules that hook into it so that any number of backends could be 
written without having to touch the ISC code.

What I would like to see happen is to expose all the parsers in used in 
dhcpd + libs as an easy to use API with language bindings for 

Not perl, but here's my python module for parsing the leases file. Attached.
