Ahh, just out of date naming i suppose. We only have the free version and Commercial Indie atm, which is essentially just commercial pro/indie. Originally we had price tags with the c++ SDK to come also, but never got there lol
We will find time to update the product name to "commercial indie" to match and will think about dropping the indie part completely. Our main market is the hobbyists and indie's as pro's usually want source access etc... but skyline is designed to offer pro tools also.
All part of being in Beta lol.
