Hi
I'm pretty sure Alex has said Quest 4 will feature pre-made containers, so I'd sit on the fence until it is released if I were you.
I did start to modify my typelib to multi user (as well almost finishing a new and massively improved version of the single player library) but then Alex announced V4 was in the offing and so I just shelved the whole thing until I see what the new version offers as inbuilt functionality - I'm not into re-inventing the wheel.
