Hello, If you are developer or a company focused on GIS/LBS, I think you might be interested in my complete Android project for sale: tripcomputer.pl This is GPS solution for off-line navigation, ready for improvements like any map support or new features. I just must work all day for my company and think, will not have enough free time to continue developing. So, if you are interested, please contact me on my email (website). Whole project can be licensed to you for any commercial use. Cheap. Regards btw: I also consider to go on GPL, but just do not know how to build community of experts willing to help with development.
