In case you find it useful for remotipart, Bifröst is an alternative implementation of a jQuery Ajax transport that allows to send both files and data asynchronously using the iframe technique, but it doesn't need the responses to be wrapped up by a textarea to parse data, so you can work with regular Rails responses (html, json, txt, etc.).
It has a set of built-in unit tests you can run to verify that data is parsed properly on different browsers. It uses Jaqen to test different types of requests and responses.
