ISO update cd image for over-network or USB upgrades?

The disk images are fine and good for new installs, but most of the other linux distros will include ISO images from which you can update a system either via a CD drive, a network share or even a USB storage device. Are there such images available for the various raspbian updates? Or are your own ch...

OK, py2exe may not be able to create programs that will run on raspberry pi, but there's no reason it couldn't create exe files that would run on a windows machine.

They say that they have to use qemu for many components which means it would run very slow on arm.
