My concern is just the reverse of what your reply seems to address: I do 
NOT want packages within the locations to which MATHEMATICA_BASE and 
MATHEMATICA_USERBASE point to be sought first by Player Pro.

I want to be able to have a separate location for, say, an encoded 
version of a package that I'm running with Player Pro, and a 
source-visible package I use for development within Mathematica itself.

It sounds then like the only alternative would be to put the encoded 
version directly within the PlayerPro tree (is there an 
AddOns/Applications subdirectory?).  So...

Will that work -- will PlayerPro first search for a package within its 
own directory tree despite settings of MATHEMATICA_BASE and 

If not, that's really bad!

If so, that's only partly good: it still forces me to put such things as 
(encoded) packages within the PlayerPro tree that might get wiped out 
whenever I re-install or upgrade PlayerPro.
