The problem with expandos is collisions with members of any interfaces implemented by a node in question. How can you have a data under a key of "nodeName", "appendChild", etc. In implementations that make DOM objects inherit from Object.prototype or Function.prototype (such as webkit) there's additional set of candidates for collisions (toString, constructor, call, etc.).
