Sure, but there are plenty of not-quite developer types using Python, plenty using locked down machines, and plenty who simply don't trust arbitrary code when it wants to elevate. The ability to become an admin does not preclude the need to support non-admin users.

This is good to know. Maybe we aren't as far away as we think.

Agreed. I mean it'll become an obvious option (one of the radio buttons at the start), and eventually the default option.
As a slight aside, do you enable the option to compile PYC/PYO files on install? Unless your users are running as admin, you won't get caching on these for the stdlib when it's installed into Program Files.
