I guess why I was asking , besides it being catapulted into the spotlight in July. I was doing some research on it.
I work for a big ecommerce/brick company so if there were other features in a Map server, that was compatible my company might be interested in it for other business needs
Also where possible I don't like to depend on outside services, they sometimes break or the needed connectivity fails and I hate telling my management I have no control over the issue. This way if they have access to the site, it should always be working
Just being Bandwidth conscious , the company can be a little miserly on allocating Internet circuits. Almost like they treat us like a brick and mortar store. So when I expect whole departments to be using it, I just want to make sure I think about what it would take when Networking comes and says its pulling to many "images"/bandwidth
Finally, just like reading on things I have not dealt with before. I figured it would be a good starting point to see what you did when the Tiling service broke, easier then trial and error
