I noted the comment above that over saturation of products is going to slow down the market.
I agree with that personally for my buying needs. I'm over saturated, so will buy less for sure. Not clear to me is whether the deluge of new products will slow down. The pace seems to be picking up.
Speaking of PACE, I'm a satisfied, ZDT subscribing, iLok user. Has worked for me. I like that it may give some software publishers a chance to earn some revenue from their hard work.
I'm thinking as an originals musician that I'm bummed by Spotify and other free streaming delivery systems that probably reduce income chances for new record releases for artists. Giving it away as free kind of is hard to compete with against a price tag. Software often is much more expensive than a song. Without some kind of registration or activation process I would think software developers can lose quite a bit to the pass it around for free crowd.
In order to help music software developers earn a living and be motivated to make the next cool release I think either the software developer's own system of tracking licenses, or handing that function off to an outfit like PACE, can contribute to the ecosystem we enjoy.
So I don't mind iLok. At least having it has allowed me to use some of my favorite software tools.
