All I want to do now (given the size stuff), is to have a function and
possibly a type to compare the 24-bit OUI's, and give the tools
in /contrib to load a table using these from the IEEE's list.

No more hardcoded stuff in the db. 

Does this make more sense?

It's definately extensible, and frees code space.
