Hello, Thanks for the responses. My question is thoroughtly answered: My idea for accepting SMS on an Internet server was of course technically inspired; I already was a bit weary about acceptance in the IETF and from the sound of it, this is not going to be easy. More importantly, I had thought about the opportune delivery of SMS to a broader network (creating money for the telco's from which they were sent) but not about the ability to also bypass the same SMS-sending mechanism. This does indeed give a strong incentive to telco's to not support it. Given that mobile users are discovering chat (although they still accept lock-in XMPP providers like FaceBook) I think we are already moving away from the problems of lock-in messaging. With that in mind, it may actually be safe to simply ignore SMS' closed setup. (It may even be a reason for countries or markets to demand network neutrality!) Cheers, -Rick
