I love the idea behind wildfly:run. It practically means you can run a pre-configured Wildfy from the sources. Tho it would be perfect to support hot-deployment for application deployed with wildfly:run (enable compile on save in IDE and compile right to the deployed folder).

In standalone wildfly it can be achieved by setting "Auto deploy exploded" to true in a deployment scanner. Difference is that deployment scanner scans deployment folder while deployment made by wildfly:run is not rescanned. Would be nice to merge these two things.
See top voted answer in http://stackoverflow.com/questions/969279/hot-deploy-on-jboss-how-do-i-make-jboss-see-the-change some guy explains his hot-deploy solution, same result with wildfly:run is what this feature request about.
