Answer 1

So far as I know, Vista allows one copy on a desktop, and one on a laptop owned by the same user. That's it.

Vista has major piracy prevention techniques.
Vista – How Microsoft Prevents Piracy

Learn what features of Vista will be disabled if the software isn't genuine
Microsoft's efforts to combat software piracy will be stronger with Windows Vista than they are with XP. Microsoft Software Protection Platform, the Vista equivalent of Windows Genuine Advantage, will virtually disable your computer if your Vista install doesn't pass Microsoft's validation test.

Exactly what happens when Microsoft determines that a version of Vista isn't genuine isn't entirely clear in the white paper describing the Sotware Protection Platform (SPP) tools. At one point, Microsoft writes that people using a failed copy of Vista will not lose access to their personal data.

Instead, they will see a persistent message on the desktop telling them the copy of Vista isn't genuine and they will lose access to certain Vista features including:
· Windows Aero
· Windows Defender
· Windows ReadyBoost
· Download Center, Windows Updates, and other updates and new releases
While a persistent message and missing features would be a deterent to piracy, there is the potential that SPP could do much more to disable a copy of Vista that fails validation. If validation fails, Microsoft writes that Vista will enter "reduced functionality mode". Once in reduced functionality mode, users will only be able to use the default Web browser for an hour at a time. No other applications will be available, as there will be no Start menu or desktop icons. After using the Web browser for one hour, Vista will log the user off without warning. The user can log back on immediately, but the same limitations apply. Since the screen shot provided in the white paper says that accessing your computer with reduced functionality will "also allow you to buy a product key online", it appears that the purpose of reduced functionality mode is little more than to provide a way for users of presumed pirated software to purchase another copy from Microsoft.

Exactly what happens when a Vista copy fails validation isn't clear from Microsoft's white paper or press release. Based on the spin Microsoft has put on their efforts to prevent piracy of Windows XP, we'll probably have to wait for stories of "false positives" to determine exactly what features (or core functionality) is lost when Vista fails validation.
