I agree with Britt. We developed a Swing framework for jbpm UI's some time ago ([utl]http://www.camunda.com/toolkit_for_jbpm/tk4jbpm_overview.html[/url]). There it would be also easy to support such a versioning of the gui IN the framework. Currently we do that in one clients application by changing Node names to "ShipIt.2", so we can configure a different panel for it. But Britt's solution is much nicer!
