Regarding the 'cache to disk' bit, is it worth it?  I would image the 
latency to use the disk as a cache is roughly in the same order of just 
making the query to the authoritive DNS server?

Now, if you are instead talking about "write the cache to disk on 
shutdown for sweet and lovely restart", that's a whole different kettle 
of fish :)

Good work never-the-less.

[1] so you don't in effect flush the cache
