True, but you ARE suggesting that Cisco produce a binary patch, to a possibly compressed image.
Like I said, it isn't trivial. For example, the patching software (this would require memory) could uncompress the image, patch it and recompress the result. As a double check it can verify that the newly patched compressed image has the correct checksum (because the compression is completely deterministic, you can do this). But this is getting into details that I, having no access to source nor the way the binary is put together, am not competent to go into in any authoritative way. However I do believe this problem can be solved. It may indeed be technically easier to distribute a whole new image. However I suspect this is harder from a management, legal point of view. A patch tool, when made publically available, doesn't give away as much information as does a whole image. And you should make security fixes readily available, to the point that anyone on the planet might download and examine them. However my main point is that upgrading, at least for the provision of security patches needs to be much easier then it is today. Both for the professionally managed networks as well as the SOHO and residential market. -Jeff P.S. I am going out of my way to "plain text" sign these messages rather then sending PGP/MIME.
