Forum OpenACS Q&A: Re: OpenACS and SMS
Hamilton Chua and Roel Canicula for outbound/inbound messages on www.e-sulat.com.ph (now defunct). Concept was a post on a webpage to SMS(?) for use by Overseas Filipino Workers to send to a relative in the Philippines and that same person can reply via SMS and it will appear in the sender's inbox in Openacs. Ham/Roel correct me if I'm wrong.
and Ham again for www.tala-arawan.net, inbound MMS messages (picture and text only) which posts to lars-blogger by crafting the message on an MMS capable phone and sending it via email and/or SMS(?)
