Xslimmer.Oh yeah...I've wondered about the same thing myself. I remember back in the mid 1990's I used to use a program called "I Love Native!" to strip useless PowerPC code from FAT binaries on our LCIII, in order to free up space on our overstuffed 80MB hard drive.I imagine if a similar solution existed for OS X, it would be possible.
It can strip all the Intel or PowerPC native code out of applications, so it should be possible.
