Please also include me.
Did one of the links you posted earlier have the license text?

Agreed. And often lots of time.

I haven't thought it was good practice to be public about vendor licenses but maybe we should consider making a list of vendor licenses we might have interest in, review them, and post our conclusions. Not legal advice obviously but public commentary on the potential problems they cause.
If we do that, we may be able to enlist some help from the other free OS people we have met over the years.
