Generalization of the protocol?

[Kixunil]

This idea was already considered by others but with one more important feature: being universal for various node applications (electrum server, bitcoind...), not just LND. Here's some discussion https://github.com/BlockchainCommons/Airgapped-Wallet-Community/discussions/33 sadly, that one received little feedback.

I still wonder if we could make this universal because I don't want to require users of my repository to pair every single application manually. It'd be much better to pair once and then just use all apps within same device.

Note that I intend to do something universal anyway - the value of it is just too high. I'm mainly seeking collaboration hoping that together we could do something better than everyone doing their own.
