I'm not sure if this was preventing anyone from using Virgil, but we added run-modes to Virgil to accomodate users that have an existing cluster. Now, you can just point Virgil at the remote instance and use it only for the GUI/REST layer and SOLR integration. http://brianoneill.blogspot.com/2011/11/introducing-run-modes-to-virgil-support.html
