Some updates on the topic.
Demo/proof of concept is complete. We have all things working: touch, screens, network drivers, harware acceleration for GPU, USB, etc.
Warning: please consider this highly experimental. Don't mess with your transceiver. Always have a backup. I play on additional SSD for all my experiments.
Please don't ask for procedures at this stage. As EESDR3 will advance to the final version I will consider to build a proper tested procedure easy to implement.
