Hey Tamas,
A shame you couldn't make the workshop, there should be some links for you to the download of them on Kickstarter. It's been going really well so far, Nate is certainly busy! 
I'll find the license for you and forward it.
Cheers!
Spine Licenses
Sounds cool 
looking forward to seeing what you come up with.
I forwarded the license emails yesterday, are you checking on sonofjanoh@yahoo.com and have you checked the spam folder ?
Cheers!
