Hi @kherman
I think the Spark core side of what you want to do is here and ready now. You just need the web page side to pull the information together.
If you look at my tutorial on getting started with Spark.publish() you might get some ideas. It would be easy to have say six cores all publishing events and have one web page listening to their event streams, with visibility controls on that page to determine what is shown and what is hidden. I am sure the folks that program for the web everyday would have some great ideas on how to do this.
