A recent patent application (via WMPowerUser.com) describes a system devised by Microsoft to enable automatic pairing of devices over short-range wireless connections such as Bluetooth and Wireless USB. With this system, after an initial manual pairing, say between a phone and a PC, would allow those devices to automatically pair with other related devices, such as a second PC.

The pairing mechanism would act as an alternative to the preexisting pairing mechanisms already built in to these protocols, and would require device support for both sides of the operation. Public key cryptography is used to securely share pairing information among different devices; that information might be transmitted via USB key, network connection or any other convenient method. The described system respects uesr identities, so merely pairing with a computer would not mean that anyone logged into the machine would be able to use an automatically paired device.

Scenarios in which suitably-enabled devices would be useful are not too hard to envisage. Having phones automatically paired to all the PCs one owns is perhaps the most obvious example of when this would be useful, but more broadly any peripheral could be used: headsets that you pair with your PC but also work automatically with your phone, mice that work with every PC you own, and so on.

Of course, filing a patent does not mean that this will ever materialize in any shipping product, and there's no indication thus far that this will form a part of Windows Phone 7 Series. That said, phones and PCs are probably the best-suited devices to this kind of technology as, being software-driven, they're the easiest to update to include this kind of extension. Seamless wireless syncing (Zune already performs syncing over WiFi, unlike iPhone), including seamless wireless pairing, would certainly be another way in which Microsoft could distinguish its phone platform from the iPhone, and would enable the company to promote the more connected, less wired merits of Windows Phone.
