That looks great
 
I have no problem with your proposal. You have put 1000's of hours into perfecting stellarium for us all at no charge. A special package like that would be great. I think you should be able to cash in on that. It is much better than the "theSky mobile" that I paid $US50 for 6 years ago. When I get a N900 I will buy a copy
