I have not tried this, so I can't say it will work. However, there is a way for one HG setup to communicate module state to another setup. If you were to do that, you *should* be able to use a local setup to control the second setup at the same or a different location. I run HG on a RPi v2 and have had very few issues that were not self inflicted. If I were in your situation, I would seriously consider using that approach.
It is possible to use the Android client to control your HG setup, but it requires a live connection to to things in real time. Prior to migrating to HG, I was running AHP (Active Home Pro) to control my X10 setup. I used the SDK that X10 released to write some custom scripts that would allow me to control my setup remotely via SMS. If you do not have a good internet connection, perhaps you could opt for a SMS modem and control things using a similar approach?
