Most Definitely Interested in something like this Limited License concept.
Seems to me, even though the OTU is "tied" to the rules, back in the day, the homebrew campaigns were generated without any of that.
So, my spin on it is, if I comrehend, these would be rules, supplements, etc as alternate settings, keeping the "Physics" and "Sciences" of Traveller, but with different histories, governments, etc. Just laid out in the same 8 X 10 subsector format, a la Spinward Marches, or some of the old FASA Sectors, yes?
If that is what you are seeking, I am all for it, both as a player / Ref, and potential contributor of material. I really miss the old school LBB / wild frontier of the "For Use With" licensees days. Not that this will be that. But, I REALLY miss those days.
No offense to d20, but level-based games and the whole skills / feats stacking just doesn't feel "Right" to me, as a player, or referee. CT was my first ever RPG back in 1977, and decades later, it's still my favorite (In it's newest guise as T4).
If others out there have ATU material, I'd love to see it, even if it is a homebrew subsector, or two, with some decent writeups, centered around a common theme, that I could either get ideas from, or use as a launching point for new campaigns.
If it is material that rivals the Environment Series, or new Rules (Such as Robots, Merchant Prince, or High Guard, say, what those did for CT, back in the day) in Style and content, I'd pay cash money, big time, to get access to other Referee's ideas on those kinds of submissions / articles / what have you.
Very Exciting to see this. I hope it comes to fruition.
