Steve Sharp, VCGI
VCGI has made some changes to our Cached Map Service offering. We’ve added a cache for Vermont’s black and white orthos in Web Mercator, which will allow you to create mashups with Bing and Google using VT’s orthos. We also corrected the projection problem with the color Web Mercator cache (Note: The last zoom level hasn’t been fully cached yet, but the bulk of the cache is usable).
You can find the full skinny here: http://www.vcgi.org/dataware/?page=./products/metadata/map_cache.htm
This is still a BETA offering, so please keep that in mind. Your feedback is always welcome.
