A nice idea would be to get a group conversation together on a call or video and have those who are really familiar with what the system can do and those who are good at exploring ideas... get them together and go over the possibilities.

Brainstorming and giving a people an idea of possibilities is always a great way to get people starting to think and imagine what they'd do.

Sometimes people don't even know what questions to ask or where to start... hearing some people talk about these things is sometimes all a person needs to realize their APP could really do something awesome.
