Hi all,

I have committed to the apache-extras repository a very simple project with
everything set to use value-proxies.
It could work fine as the basis of how hupa can use them.

just check it out and run:
svn co http://svn.codespot.com/a/apache-extras.org/hupa-evo/experiments/rf
cd rf
mvn test
mvn gwt:run
