Started to experiment with lnproxy on the #Raspiblitz: https://github.com/rootzoll/raspiblitz/pull/3637

Using it already as a gateway node:

can hide the pubkey of any nodes behind one that is already known.

For a public service follow the privacy best practices:

Tor-only, channels from peers, coinjoin.
