1. Well the guessing period is over. And since the app is Sun’s, I don’t think Jonathan needs to worry about the “use of someone’s mapping application without attribution” comment.

2. Speaking of the map, you do say that you are using google. I still don’t see an attribution to them, so that one comment is still valid.

   On the performance front, we quickly realized that the JavaScript-based markers often used for such mashups just would not work for a large data set such as this one (80,000 registrations and counting). So for our high-level views, we use the Java Image I/O API to create our own matrix of tile images, and then use Google Maps API calls to have those overlaid atop the normal map tiles. For example, where a fully zoomed-out view of the earth would cripple one’s browser with the work of placing 80,000 individual “balloons” on a map using JavaScript-based markers, the custom tile approach means the browser just has to retrieve and position at most a handful images. Much faster and kinder to your browser.

   it’s called “grouping” you knob. Maybe you should be checking out mapstraction.
