Wondering if it would be worthwhile to include other services (via guides) to install on the pi in addition to Peerbox? For example, something like pi-hole to block ads and another service for vpn? This way users not only can generate coins by minting, though they can improve their local network security.
This would show the minimal computing and space requirements of Peercoin minting. Also opportunity for marketing if can get Peercoin listed on pi-hole site. Something like not only block ads, though get 20 PPC for installing Peerbox and minting.
