Sounds good. I just want to add that sometimes it's not about "wanting to write closed source apps", sometimes it's more complicated than that. Like, the app integrating with other systems that can't be GPL'ed, or just lawyers not willing to take a chance in cases where it's not immediately obvious what's GPL compatible.

Sometimes companies who love and contribute to open source just can't use GPL'ed software, for technical reasons, for lawyer reasons, for FUD, etc.

I, for one, think it would be an awful shame for your cool tech to not achieve the adoption it deserves, just because of GPL.
