The main use case is to post image/video to the Wiki/CMS. However, I have a case, where it would be better to save to the desktop. The person will then use in offline documentation (well, homework, really!)
We could save to the Wiki/CMS and then, proceed to download the image/file, but maybe it would be better to do this via jCapture directly?
Thus, on the interface where we pick the name of the file before it's uploaded, there could be a "save as" interface
On a related note, the saved .swf could be converted to HTML5 via https://www.google.com/doubleclick/studio/swiffy/
