modern-ui

If I start a modern-ui app and then switch to a different app or a normal program running on the desktop, what happens to the first app? I've heard something about the first app being suspended, but realized that I don't really know that for certain.

I mean, could you write a SETI@Home (BOINC) app if you wanted to, or will apps that aren't in the foreground always be suspended? Can you change that? I could see changing that based on available resources, running from AC vs. battery, etc.

This morning I heard about an iPad being recovered thanks to the "Find my iPad" app, and was wondering whether you could write such a thing as a modern-ui app and have it work without being the running foreground app. (I'm aware that you'd just write a Windows service or similar, that's not what I'm asking about.)

It seems like a basic question, but is there a way to run Windows 8 (Modern Apps) in Windows 7 (without a VM, that seems like cheating)?
