see would be to name based on treating "community supported Koha" as the 
original, and the PTFS versions as forks.

While I understand the situation is slightly more complicated than that, 
it seems like a good approximation. A fork indicates some difference 
from the original without making any implications as to superiority 
either way. Calling original Community, on the other hand, does imply 
inferiority for me due to its use in other projects, as pointed out by Reed.

"Community supported Koha" could be referred to as simply "Koha" for the 
general public, tacking on something like "Standard" or "Trunk" as 
appropriate for the audience when necessary to make the distinction 
clear, and the PTFS/LibLime versions as "PTFS Enterprise/Harley Koha".

My two cents.
