It's a neat idea on what you're trying to do. However, if you're going to crop a picture to 1536x512 pixels, you'll probably be on a PC (how would you even view a 1536x512 pic on a 640x480 screen and see any detail). I'm pretty sure that having a ppc program convert a png to qtc manila file would take a long time. It can take a minute or two depending on the processor in the desktop (times 3 or 6 images), and our phones are a lot slower.

IMO, a better app would be one that would let you preview a sample of a panoramic pic (maybe just read the first qtc on the ppc), select the panoramic image you want, and have your ppc app copy the manila files to /windows and restart manila automatically. You'd still have to have users put the 3/6 png's into the manila files and transfer them to a folder on their phone that is read by your ppc app. This would be easier and quicker than installing/uninstalling cabs to change pictures (and you wouldn't need to create cabs in the first place).
