One thing that I kind of really love to have as a scripter/creator is a sort of unique SL browser functions. So like, for one example, when going to the SL site, maybe it can sort of auto-log us in.. that will also cut down maybe on scams as if someone opens it in the in-world browser, it will auto login them in if it is real, and if not.. its su.s But more than that, I think it is something that you can walk by an in-world browser or open a page, and it will be able to tell who the avatar is accessing it (maybe with a unique key that is not their normal key for privacy reasons. The main reason I think about it is things like redelivery terminals that will give you personal content, and maybe also stuff like RP systems working on the web that can be integrated to show personal content in the world (like your character profile) and make it all smooth. This should have privacy options if someone prefers not to use it.
