the problem is that the Image.show() command is pretty much a hack
to make life easier. it saves the image as a temporary file, then
launches a standard image browser in a separate process.

this will not do at all for any kind of realtime system.

your best bet is to use PIL's interface to Tkinter and make your own
small gui, then i believe you can display the PIL images directly in
the gui. (saving the save, launch process, load steps)

i still don't know if that is going to be fast enough? not because
PIL or python are too slow, but because thats a lot of image data to
be analyzing and processing realtime
