The other place where I wanted to control this is where my GUI app, which runs as a 32-bit process on Leopard (which can be influenced by LSMinimumSystemVersionByArchitecture), launches a helper (today via exec), and I'd like to run the helper as 32-bit on Leopard too, 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.
