That's really the gist of this. I still (it's 2012!) can amaze/scare/shock people by sending mails as their so/dad/uncle/lover/boss. SMS is just the same and for just the same reasons it's 'okay' (the usual use case is beneficial: I might want to send mail and define the from header. I really might want to send a text message from a website that looks like it came from my mobile, and leads replies to end up on it). Can we solve this at all?
