The role "skill developer" is rather too narrow for me. Jibo ecosystem should provide many creative people (commercial developers, hobbyists, students) an outlet to contribute to both skillls, but also the asset store - if I understood that correctly. Existing asset producers (pros, hobbyists) might find it easy to move into the Jibo ecosystem based on their experience/business in other ecosystems.
As in other ecosystems (gaming, graphic, animations,etc ), members are both consumers and producers. A consumer might need a skill or an asset depending on their needs or interests. There are many goods and services that can be provided not only to the Jibo end user, but also to the hobbiest as well as the professional developers. I'll perhaps download/buy a useful skill as needed. However, to support my development for demos/prototypes, products -I might license assets such as animations, graphics, audio, behaviours, and even supporting software components (connectors to this and that...and so on).
I expect other groups will evolve later as desired -right now, it's a good place to learn, share knowledge+learn, and slowly build a community, and potentially find collaborators...
Anyways we'll learn more about asset SDK and stores. Speculation for now about store composition. My thoughts follow the trends I've seen. Please correct any misstatemensts on my part
