Web-based deep zoom for large TIFFs (like Google maps)

We generate large image files, of which a sample can be found at <[login to view URL]>. We now wish to host these files through a web-browser interface. We do not permit Flash or Silverlight-based solutions, but you may use HTML 5 if so desired. It is understood that pre-processing of these images will be required in order to create a deep zoom tiled stack (as explained at <[login to view URL](silverlight-quickstart)#creating_a_deep_zoom_image>). This pre-processing algorithm should be part of your solution and needs to run on Windows, e.g. using a scheduled task. We prefer solutions in .Net and/or PHP. jQuery, AJAX and other client-side technologies are all permitted (though must be able to host locally; in other words, Google APIs that require a key are not permitted). Examples of proprietary viewers are: <[login to view URL]> <[login to view URL]> <[login to view URL]> (free registration) We only care about viewing capabilities at this point. Additional features (including cloud capabilities) will be developed in future projects.
