Yeah, we can distribute an original interface to an LGPL lib. We have to
make the user download the lib by pointing to it from a web page or doc
or a non default part of our build can auto get it if we alert the user
of the license of the piece thats being retrieved.

I believe that the LGPL people think that its fine to include with
Apache stuff whole hog, but Apache does not agree - so we have to do it
that way.
