Allow anonymous users to post via SMS, email

A comment on the following forum topic led me to this module, which is close to what I am working on, but not quite. Not sure if you would expand on this module to include this functionality:

Creating Twitter-like functionality for Drupal
General discussion

I love the power and simplicity of tools like Twitter and Posterous that allow people to easily post content from email and mobile phones.

What I would like to do is to capture some of this power for a local news website I am building in Drupal.

Specifically, I would like to enable anyone to send text or photos via SMS or email to the site and have it post to a Community Pulse page.

Allowing anonymous users to post this way would be very powerful, and it would seem very simple to modify existing modules to enable this function.

The hard part would be to keep this from becoming the mother-of-all spam magnets.

There seems to be a few ways to limit the problems. One way would be to send all first-time messages into a moderation queue. Once a message is found to be legitimate, then all messages from that address/number would be OK'd to post without moderation. Senders who aren't legitimate can be marked as spammers, and their messages automatically discarded so they don't clog up the moderation queue.

I'm not a coder, and setting this up is a bit beyond my abilities. But I'd be willing to chip in some bounty money to see it built.

Is there anyone else out there interested in this kind of functionality?
