I don't know what Chris was referring to, but one option would be to 
write a small CFM wrapper (which would require CodeWarrior), and have 
it simply load and call a Mach-O executable using things like 
CFBundleGetFunctionPointerForName (). I've used such a scheme in CFM 
plugins to call parts of the OS that were normally only accessible 
from Mach-O.

The problem is that if you did this with a plugin, you'd have to have 
your CFM wrapper put CFM to Mach-O glue around every callback 
function you called, and wrap all your callback functions in Mach-O 
to CFM glue for Photoshop to call.

So it can be done, but is hardly ever worth it. And, since it still 
requires a CFM piece, you still need to have CodeWarrior, so it 
doesn't save you from having to buy it (which will still be cheaper 
than the time you'd spend wrapping all those functions).
