Keep in mind the bandwidth is pretty limited. Even a single page view takes a fair amount of data these days.
However, signed packets do not violate the HAM rules, and is pretty common. People controlling systems (like repeaters) can ssh to them, with encryption disabled (there are patches), but still using signatures to avoid worries about packet modifications.
js8call for instance can do "mesh" networking, but the bandwidth is a few 10s of bytes per minute. But you can send messages through multiple hops to allow things like getting messages through to people you can't directly contact.
