OpenBSC and MMS

Hi all, I would like to test sending MMS messages to mobile devices. Out of the box I know OpenBSC supports SMS, which I have been able to use, however, I feel that MMS will be more tricky. My initial thoughts are to set up OpenBSC with GPRS using this: - http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS And then try to bolt some kind of MMS support on top. Before I get started though, I was wondering if anyone had done this before and/or had any ideas as to how I might go about implementing this. I really would appreciate any guidance anyone could offer me. Thanks in advance, Simon
