Hey, I forgot to mention KSS. While its Grok support isn't as polished yet as we'd like, this might also be a way to get to rich client applications with Grok. See http://www.kssproject.org and http://svn.zope.org/megrok.kss/ Ah, I see it has had a recent release: http://pypi.python.org/pypi/megrok.kss Regards, Martijn
