The only non-standard part of Apple's charging scheme is the shape of the connector. The AC->DC adapter part is a standard switching power supply, the request on the USB end of the charging cable is compatible with USB Power standards, and so on.
The really proprietary parts of Apple's cable are the bits associated with the data interface (digital audio, control systems, accessory systems, etc.); which is frustrating, but not really surprising at this point considering the 30-pin connector they replaced has been around for a decade.
