Heatmaps and ArcGIS Extension to the Google Maps API

Hi there,

I'm very interested in learning how to generate heatmaps utilizing the ArcGIS API, particularly in conjunction with Google Maps. I've done some searching and the only relevant thread that I found was here, yet there is no real discussion of implementation, usage, etc...

From what I've read, both the Flex and Silverlight APIs have methods that can be used to generate heatmaps and I was wondering if the Javascript or Google Extension APIs would be receiving equivalent method calls in the near future or if there is a work-around that I am unaware of.

I'm still new to the Google Extension API and mapping in general, so please forgive my ignorance if there's anything that I've said should be blindingly obvious. Thanks!

As a follow-up, I have heard nothing on the front of using the ArcGIS Javascript API and ArcGIS Server to generate and deliver server-side heat/density maps. However, thanks to Patrick Wied and inspiration from his client-side Javascript library, I was able to put together a demo of client-side heat map generation here.

Basically, this mash-up creates a colorized image using the <canvas> tag and then applies it as a GGroundOverlay (Google Maps API v2) to a Google Map. Currently it only supports non-IE browsers, but I am working on integrating excanvas.js to support IE 7 and 8.
