Ask HN: Can anyone reccommend a good way to publish MMS messages to a web page

A client brought this up to me yesterday. She seems pretty set on it being doable, but I can't seem to find a service that meets the client's needed criteria:

1. Client signs up for a service that gives them a number to text to. 2. Client makes text # public (on contest page) 2. User takes a photo with their phone 3. Someone then texts it to a number (I am highly recommending that the client admin the photos) 4. The service (whichever it may be) then takes the mms and gives the developer a way to access the texts and output them on a page.

Thanks in advance, if anyone knows.
