Linden Lab has selected us as second round beta testers for Experience Keys.
Experience keys allow avatars to grant global permissions to an experience. This makes inter-sim teleportation possible, allows temporary attachment of HUDS and things like backpacks and weapons, and allows interaction without an avatar having to sit. At our robot sanatorium we could, for instance, cause an avatar to slip and slide when he or she steps in the pool of oil spilled on the main floor. Until how we have had to rely on blue menus-- which rather detracts from the experience.
Sweetie and I have been staying up night thinking of ways to use the experience keys.
