A far-fetched suggestion:
Could there be any way to integrate the testing server to activate when launching the krpano application?
Sometimes {or maybe very often for some users} you need a client to view the pano on their own computer...and depending on their browser that might not allow local viewing, they might not be that smart to go and launch the testing server first to enable local viewing let alone to fiddle with the flash application. So any way to include that functionality in a, maybe secondary version of krpano.js or swf might do the trick.
