How do I create a TypeLib for UDTs in VB6?

it's not really practical to keep the registry clean on the development machine

I tend to agree with you, but I do think that's the point to which Bonnie was referring.

my question is really geared at deployment

As long as you toss the superfluous DLL that was created, and just use the TypeLib, there shouldn't be any registry consequences to deployment.
