In Apple's continued endeavor to become even more detached from their customer base, it seems the company is pursuing a new form of DRM technology similar to WGA. The new technology which Apple recently applied for a patent with, is intended to lock an application to specific hardware.

In fact, in this sense the technology seems even wider in scope than WGA - they want to encrypt applications and platforms, rendering it impossible to run their software on any hardware they do not whitelist.
