pemerton- I'd answer, if I understood your question more clearly.
My main question is this - when people like the OP express concern that WoTC is trying to tighten up its control over 3rd party publication and distribution of D&D material (examples normally given are things like changing "Dryads" to "Blackwood Dryads") I assume the main issue that is being raised is the issue of trademark infringement and the tort of passing off.
Is this correct? If so, would it be sufficient to avoid such wrongdoing for a 3rd party publisher who wants to use Blackwood Dryads in an adventure to include a statement prominently in their book saying "We are not WoTC. "Blackwoods Dryads" is a trademark of WoTC. Our use of this trademark is not intended in any way to suggest that we are, or have any affiliation with or licence from, WoTC" - or similar?
Of course, the OGL would make the above disclaimer irrelevant to the extent that it licenced use of certain trademarks.
I think none of the above would be relevant to homebrews or non-commercially distributed material, because in that case there would obviously be no attempt to pass oneself off as WoTC in the course of trade (or does trademark protection extend to non-commercial distribution?).
There is also the issue of copyrighted text, but I see that as less of an issue because most adventures or homebrew work is not going to reproduce any of WoTC's text. (To answer one of Third Wizard's questions, I think the OGL will probably require 3rd party modules to refer to a particular page of the MM, or to reproduce an abbreviated stat block in a mandated form, rather than allow them to reproduce all the monster stats and text.)
An exception might be a PC generator, if it reproduces feat descriptions. In this case my intuition is that home brew would be OK (fair use, given the intended use of the book as sold by WoTC) but either commercial or non-commercial distribution would be a copyright infringement.
Is that any clearer?
