I can implement all needed for planetariums in... well... 6 months. Do you want to delay SE and game development for 6 months? No updates, work focused on planetariums only. Quote Liam7405
planetariums would be encouraged to fund it
No, they wouldn't. I know about this market a bit... Well, it's just a market. no one needs a beta program which is in development and needs educated specialist to work with it. And of course they will not fund it. They needs a program which is working "from a box" and have simple interface understandable for lecturers, even better if it will resemble interface of the most popular programs. Just buy license and work. Anything else doesn't matter.
