Erlang - Remote communication, response

Failed to see this mentioned anywhere in the documentation but if a node remote communicate with another node can the receiving node respond to the sending node simply by using the PID contained in the "From" variable?

Yes, see the documentation for erlang:send/2,3, which says:

Dest may be a remote or local pid, a (local) port, a locally registered name, or a tuple {RegName, Node} for a registered name at another node.

Here, Dest refers to the destination of the message, and I highlighted the word "remote" in bold to show that a destination PID can refer to a remote process.
