also, making rendezvous paths for hidden relays is not a big extra step too...
i think if the traffic volume is low, and it's primarily for internal access and you don't have a concept of outbound routing it could be quite interesting project
i know i could build all the pieces but it would probably take me a year to get to a decent beta product, maybe less if i happen to be able to find some competent golang/bitcoin/lightning/nostr devs to work with me
