a channel in this case is a set of friends who are on one common preshared key (and a hopping set of frequencies). So each mesh only cares about (or even sees) packets on that mesh.

Lora is quite a slow bitrate protocol (but it has _great_ range and super low power needs). So we are focusing on our smaller use-case at first (in the interest of speed of development and stability for users)
