Now that this has some attention, what can people like me and other readers do to help you get this over the finish line?
(thank you!)
Long story short, I have been working which the Chatty developer to integrate MMS support into his program:
https://source.puri.sm/kop316/chatty/-/tree/wip/sadiq/mm-acc...
The primary program for MMS support is here:
https://gitlab.com/kop316/mmsd/
I have a few TODOs on that (which I haven't had tine for recently, but I should be able to get back to it this week). There's a few TODOs in there, so maybe work on them? (But then again, it's more a function of working with the chatty Dev than anything else).
Help testing and refining the code is also welcome too!
There is also a Matrix room you are welcome to join if you want to help, or to see how things are:
I haven’t tried mine nowadays, and there is always great progress when I check back, but I simply can’t imagine using it as a daily driver.
