And GAMA and the GPA are very much "soft" organizations - being concerned primarily with information exchange and PR (important, but not the only issues). The Association for OGL Publishers is both much more specific and aimed at providing much more real-world support once fully established. However, just as with websites like this, they should complement each other rather than conflict.
I'm not sure how you get more "real-world support" than the things GAMA and GPA do. The former is a fully professional trade organization, coordinating awards (the Origins Awards), an industry trade show (the GAMA Trade Show in Las Vegas, which any serious D20 publisher should attend, member of GAMA or not -- and you don't have to be a member to go), and a consumer trade show (Origins). They are working on another trade show in Europe, to help grow the market further by providing more opportunity to communicate directly with European retailers and distributors. GAMA's membership includes not just manufacturers of all stripes, but retailers and distributors (albeit not as full voting members), including members of those groups serving as industry officers. With the help of some very generous retailers, GAMA has supported retailer oriented programming -- helping stores run their business better concretely improves the industry for everyone.
The GPA is more informational in nature, and more geared toward new/starting companies. It's a great networking tool, for learning more of the basics of the biz, getting connected to printers and the like, etc. The GPA also has at least in the past arranged shared booth space, so even if you couldn't attend the GAMA show in Las Vegas, for example, you could have your items in a booth with other GPA members for the buyers in attendance to see.
Why has there not been a D20 specific committee or sub-group in either of these organizations? Probably because no one working in the D20 field considers it necessary. The hard stuff -- things that require budgets, staff (GAMA has multiple full-time salaried employees), etc. -- is already covered by GAMA. The other issues (sharing information, debating the license, collaborations between companies) happen naturally without any kind of organization, in places like this forum, in private exchanges between publishers, on the OGL mailing list, etc.
So...well, I don't see any need for a new trade association, and I can't imagine it being worth any dues, since I don't really know what it could start up and do better than existing organizations (or better than those orgs could do if their members decided it was worth doing).
Out of curiousity, who do you have signing on at the outset? I assume that before launching something major like a trade organization, you've already talked with some other publishers behind the scenes, so you'll have a core of interested parties to rally further interest and lobby people to join, yes?
