well, there's $SOFTWARE_HOME/Extensions and $INSTANCE_HOME/Extensions
if you're using INSTANCE_HOME.

nope.  If you want code that's only accessible to a Product, why are
you using External Methods?  Why not just define a method in
the appropriate Product classes? Or a function, if that's more suitable?

Sure you can. I do it all the time.
Do you have an example where this doesn't work?
