I hadn't yet thought about all this yet, what, with the massive shift from the desktop to Metro in Windows 8. However, as MSDN explains, Metro applications in Windows 8 can only be installed through the Windows Store. Sideloading will only be enabled for enterprises and developers. I'm also fairly sure the relevant registry key will be easily toggled for us geeks.
"All roads, as the saying goes, lead to the Windows Store," Microsoft writes, "For Metro style apps, that is, the Windows Store is the only means of general distribution (enterprise customers and developers can bypass the store to side-load apps)."
