So, feeling stupid (more than normal) for starting with ZNC (Zeronet Conservancy), ZNX (ZeronetX) is now packaged.
Ignoring the vagaries of P2P and Tor, this does seem to be viable.
Git repo : https://git.cloudron.io/timconsidine/cloudron-zeronet (same) has been refactored into 2 folders, ZNC just in case someone feels they want to take it over / use as a base, and ZNX.
Docker image: tcmbp132021/cloudron-zeronet:v3.0.0
ZNX actually allows an ID to be created and ZNX-leaning sites seem to be alive.
I absolutely see the value of Zeronet for different uses, including hiding in plain sight (for legitimate reasons), and it seems usable enough. Old/abandoned/un-peered sites can be ignored. Set up active sites.
Haven't yet found a site to promote relocation of No.10 / Millbank PHQ to central Tehran, but I will keep looking.
