Hi there! We're doing some work on SMS framework, since we've chosen it as the basis for some mobile work we're doing. Ultimately, it is a good framework, and better suited for extensability than SMS gateway.
Tylor has been working on it for the past couple of weeks. One of the main things we've done is add hooks for receiving messages (a la sms gateway), so that we can do interesting things like allow processing by other modules when we receive an SMS (or MMS) message.
We've contacted Will to be a co-maintainer of the module. There are several feature requests / patches in the queue already.
We've got a test site up, and hope to be able to demo what is essentially a Twitter clone in a few days.
Anyone working on SMS features, please review the issue queue and post other features you're interested in. We'll be fleshing out additional features that we need and posting them all there.

Looking forward to it!
As an organization with 96% client adoption of SMS, I look forward to integrating the "new and improved" SMS framework into projects at the University of Lethbridge.
This sounds excellent
I can't wait to try it out - great that this project isn't dead.
Tylor just committed this
Tylor Sherman is now a co-maintainer and just committed all our changes and contributed bug fixes: http://drupal.org/cvs?commit=118042
Please http://sifttool.com to kick the tires a bit. There is also some configuration here, like creating a "microblog" CCK type and some other stuff, but we'll work on documenting our recipe and lay out some other things that are possible to be built around this codebase.
We also potentially have access to a free SMS gateway for selected people for testing (especially if you are in Canada). Contact me for more info.

Is that for Drupal 6?
I'm looking for a way to let anyone post a short node to a site via text message.
D5 for now
But if you help port it, we'll commit it. See http://sifttool.com/microblog for an example of this working
thanks boris
