The obvious best structure is a Radix-tree (aka Patricia tree), as per
the BSD-4.4 routing table structure.

However, I'm not sure how that could be mapped to a disk based structure;
it's already been highlighted that having to (re)load an entire config
each time would be troublesome.

Brian Blackmore asks how big lists can get: At work we have over 40 seperate
network "blocks" (big ones and little ones) that comprise "local" people,
which might want to be used in an "allow relay" acl.

I'd be surprised if, somewhere, someone hasn't already solved this.
