Also, what would be the legal story on purchasing a Retail upgrade and using it to upgrade a OEM version of XP? Would it then be licensed to move around as needed, or would that only be if upgrading another retail version?
"Legal Story":
Consider what the "Upgrade" license is for: It's a license to upgrade a PC that already has an existing license for a previous OS.
You can uninstall (or just delete) the Upgrade and put the Upgrade on another PC. But the new PC needs a base license for a suitable OS. You're not moving the whole (upgraded) OS from one PC to another PC. You're just moving the Upgrade license.
That new PC needs an existing license for a suitable OS, and it can't be the license from the first PC because that license is OEM and can't be transfered to another PC.
If the original PC has a RETAIL license, then, yeah, you can move both that license and the Upgrade license to the new PC.
