Hey Andrea, I would like to grab your modified memory datastore to use as a teaching tool for the FM branch. I need to communicate the three FeatureCollection implementations needed for a DataStore implementation to rock, and having any kind of index is one of the ways to do this :-) >> 2.

If you want to grab some volunteers we can set something up again, right now we are trying to grab the developers in from some RnD branches so we have more people to help. Jesse did make a test example of a Swing panel hooked up with the steaming renderer. Perhaps this would serve as a good demo or starting point.
