It might be nice if we could set a Wireframe field for our avatars so instead of everyone our skin everyone, including ourselves, would see our avatar mesh in wireframe.
I was must watching a video on youtube of another virtual world with some of the avatars showing their skins and some their wireframes. It was kind of neat looking.
Of course, this would have to rank a bit lower in priority than sim border crossing, object rezzing time, gray textures, teleport failure, inventory loss, etc.
