Most of its clauses are benign because they do not place any additional restriction on redistribution. Clauses 1,2,3 actually restrict the possible redistribution restrictions, so they're our friends. Clause 0 is only a preamble. Clause 4 is just stating some common sense. But there is one annoying clause, that is clause 5. This is a plain advertising clause. However, I think that is not an issue because it is not said anywhere that the license addendum itself applies to derivative works. The LGPL applies recursively to derivative works, but AFAICS it is not said anywhere that the tvmet license addendum applies recursively too. In other words: clause 5 only forces _us_ to advertise tvmet (which I intended to do anyway, see TODO), but we don't need to force this advertising clause our own users. So I think there's no problem. Cheers, Benoit
