I'll be moving to SL3 in the next two weeks and will make sure I migrate some good samples as well. It is very similar however I'd ditch the whole token request thing for Bing Maps for their up comming appID ASAP. I'll most likely use OSM as the primary
example for the core DeepEarth map and use the Bing Maps control to demo Bing Maps imagery. This should keen the examples really simple.
Essentially we have been quiet building a bunch of cool stuff but really wanted to wait for the Bing Maps release this quarter to do final examples / upgrade / documentation etc. It really is very exciting and I've been working on this 12+ hours a day.
