jasgot,
I too have a single license SC. I had thought about that same thing happening to me, so on my master PC as well as the server on which I run SC, I have installed LogMeIn (free version.) Both LogMeIn and SC work fine together with no issues, and I can connect to either system with LogMeIn if the situation you experienced develops.
Hope this idea helps.
