2.k: You must not provide any feature that alters the shared experience of the virtual world in any way not provided by or accessible to users of the latest released Linden Lab viewer.LL will break many of TPV features in the next few days. So goodbye region windlights until LL's own viewer gets that feature ... if it ever does. Region windlights were an extraordinary boon to the arts community. [EDIT: see discussion in comments.]
The announcement adds,
We encourage Third Party Developers to continue innovating with unique user interfaces, niche features, and ways of interacting with the virtual world, and we look forward to working in partnership with developers on ideas they have for new or improved shared experiences for all of Second Life. We want to incorporate more innovative new features into Second Life to improve the experience for all users, and we encourage TPV developers to submit proposals through our standard process.Yeah, right. It's horseshit. Basically all TPVs are allowed to do is tinker with the user interface and a couple of other things. And as I read it, if the TPV developers come up with ideas, basically they have to work for Linden Labs for free.
