Personally, I have no problem with the implemented protection system. I MOST definitely would NOT want any type of dongle [iLok, etc] to be used.
I very happy that AlexB was able to find a way to improve his libraries [and making them available as a free upgrade]. I would be quite surprised if additional updates would be coming [mostly for the sake of project continuity]. I would welcome supplements to the current libs, such as expanded 'Q' parameters for a given equalizer and such].
