title: Real time UML class diagramming tool for concurrent editors?
body: <p>I'm looking for something similar to Google Docs, where you can work with other team members simultaneously for class diagramming.</p>
  
  <p>I've looked into Creately and Gliffy, but neither support concurrent editors for a real time project.</p>
  
  <p>Does anyone know of any good applications supporting good diagramming as well as concurrent edits?</p>
