The set of dictionaries that I tried out, had a bug and were not
fully functional. What I could see was impressive, but the program was
not usable. They were supposed to fix that bug and market them, but I do
not know the current status. The dictionaries themselves were established
dictionaries in print (like Brown, SankaranaarayaNa, Sabdaartha manjari
etc).
Also, I am not sure if palana mentioned this, but 'eenaaDu'
published a paaribhaashika padakOSamu for use by its writers. I believe
that was developed by boodaraaju raadhaakRushNa.
