Tim, Here's a thought. GWT uses <entry-point class="some fully qualified class name" /> to identify and initialize modules. Perhaps something similar could be hooked into LiftFilter and an entry point class identified in web.xml. There should be little objection to xml configuration, as opposed to using Java reflection.
