Aaahhh, herein lies the rub. If memory serves, CA's patches simply replace files completely as opposed to patching. Of course I have nothing to base this next bit on and it's pure conjection and assumption, but I bet if they used something like RTPatch or another tool, they could probably cut that 600+ meg way way down to something smaller, something much more palatable for our low-bandwidth users.
