Hi, We are considering moving to SEAM as the web technology for our jBPM web console.  The main concern is that this introduces a dependency on a Java 5 JVM.  Note that this dependency will only be there for the web console.  NOT FOR THE RUNTIME ENGINE.  In case your deployment platform is a Java 1.4.2 JVM, you can still run jBPM there and deploy the webconsole on another JVM.
