Hi: thanks. have some questions:
1. are all Open Source softwares free? free also for commercial development 
& distribution?
2. the 3-rd party developers providing tools for such OpenSource softwares 
may not be free. correct?
3. is there any possibility that an existing OpenSource s/w can become 
proprietary in future?
4. is it a good idea to use Open Source softwares for commercial 
developments? what if the project is closed and/or there is no support?
would like to give any more comments regarding this issue?
thanks,
sudesh
