Hi Grant, thanks a lot for your feedback. If you experienced the power of low-cost hardware, Bitcoin and Lightning, the primary goal has already been achieved! :-)
I am working on the updated RaspiBolt guide right now. It will be a combination of this guide, “Getting ready for Mainnet” and my Thundroid guide that already…
yes there will be a mainnet version, once Acinq releases their official release. It should be possible to run it on mainnet, but you need to alter source code and compile the lightning daemon yourself. There is no help from me or the developers to be expected.
