Dave,
You can have multiple logically separate name spaces of finite size and
all fit them into a single 32 bit ID space.
For instance, this can be done by making the 32 bit ID space identify
the name space using some small number of high order bits, and
leave the rest of the bits to each namespace.
As long as you don't have to support 4 billion interface IDs or site IDs
in a single box this shouldn't be a problem.
