VMap0

I'm downloading vmap0, however the licence is very problematic,
especially since it doesn't seem to be easy to separate non-clean parts.

How big are parts claimed by ESRI ?
How can I get rid of them ?
Have anyone done so already ?
Is anyone distributing vmap0 with ESRI parts removed (and
optionally replaced by something copyright-clean) ?
If not, should we do so ?
If we're going to distribute patched version,
should we also convert it to some nicer format ?
