yes, subprocesses are necessary to keep your processes readable (like in regular programming). You could use the APRE for remote tasks. or things like : http://www.openwfe.org/docbook/build/ch18s04.html There are different possibilities. It depends on the environment and the programming language you're using for each 'remote' tasks. You could even push a process definition for execution on a remote engine (but that's probably overkill).
