The other place where I wanted to control this is where my GUI app,

mainly because I don't want to be the reason the 64-bit frameworks
are loaded in.
For a drag and drop type install, LIPO isn't an option.
If you really want to do this, you could just ship two executables for
your helper tool in your bundle. One ppc/32-bit intel, and a 64-bit
intel. Then you only have to code for some mythical future system
where you test if it supports 64-bit intel, and exec the 64-bit intel
executable, else exec the combo executable.
