No current plans. Might you consider contributing some of your findings to Virgo even if only to get that documentation started? (Rhetorical question really - no pressure to answer here and now!)
btw. Got dm-server test framework to work with maven. Looks very promising! Now able to test without deployment to dm-server.
Any plans on documenting this framework a bit more? Got bit with placeholder value in com.springsource.kernel.userregion.properties.base Bundles. Framework replaced placeholders for test.config.properties but not for user region.
