I've put an initial version of this validator at the following URL (manually constructed since the link isn't active yet -- may have typos).
http://cvs.sourceforge.net/viewcvs.py/jsf-comp/componentsandbox/src/java/org/apache/myfaces/custom/comparetovalidator/CompareToValidator.java It'll probably take a little time for the link to become active, so you might have better luck grabbing it from jsf-comp cvs directly. Make sure to get at least Revision: 1.2 as I added the documentation in that revision. I can also email it to anyone who wants it.
