For anyone interested I'm collaborating with a great all round engineer/coder on a new project called MyComm at https://hackaday.io/project/11802-mycomm It's similar to the sat.Send concept but we decided to make it a standalone device with its own touchscreen interface and solar charging so that it can be a really reliable and accessible device. sat.Send never progressed as I wanted it to and working with someone else really helps to stimulate the brain cells and keeps driving things forward, we've already made good progress with a prototype so I hope you can check it out.
