I'm pretty sure I won't need this as my later comment mentioned. So don't worry about this for now.

This brings up another question. How does my subsystem know what the process type is? Is there an API or other way to know if it is deployed in a Host Controller versus a Standalone server (and I suppose you'd need to know if its in a Domain Controller, too)?

I will let you know about backporting. Not sure yet if we need it.
