When you say "packages" I assume you mean "packets".
Heartbeat does communication within a machine by local domain (UNIX
domain) sockets for IPC.
Communication between machines is done by plugin. If you wrote another
communications plugin, you could talk by something that didn't involve
sockets.
Those are found in the lib/plugins/HBcomm directory.
The management daemon also talks across sockets, but that's an optional
component - which if you don't want the GUI, isn't necessary.
