Javascript plugin for cross-browser range

Question

Is there cross-browser javascript plugin (jquery/any js library) for handling ranges, especially Firefox's range object(https://developer.mozilla.org/en/DOM/range) and Internet Explorer's TextRange (http://www.webreference.com/js/column12/trmethods.html)?

Thanks Srikanth

I''ve written one called Rangy: http://code.google.com/p/rangy. A now-abandoned project with similar goals is IERange, which provides a DOM Range wrapper around IE's TextRange.
