The hitch I ran into which led me to post the question stems
from the fact the FSFindFolder() returns nsvErr if the volume/
domain you request is kUserDomain.  For something like the
preferences folder it's OK, you get the user's preferences
folder with kOnAppropriateDisk.  However it means there's no
direct way to get the user's ~/Library/Application Support
folder, because kOnAppropriateDisk there gives you the local
machine's /LIbrary/Application Support.

FindFolder() -does- work well with kUserDomain (at
least there's no error and a valid FSSpec can be built). 
However if you then try to convert an FSSpec based on
FindFolder's returned values to an FSRef, FSpMakeFSRef()
will again return nsvErr.

I'm now just building hard-coded subpaths based on stems from NSPathUtilities.  I hope it's true that using a hard-coded
"Application Support" string will work even in other locales.

Thanks for discussion,
Chris
