Hi,
I have made prototype extensions for Firefox and Chrome related to this
project.
These extensions port jQuery.IME completely to the client side and can be
installed in the browser.
These extension would allow users to use multilingual input methods on any
website and not just on MediaWiki enabled websites.
Source code and installation instructions are available at:

Let me know if you have any queries. I would love to get some suggestions
regarding how to improve these extensions.
