Most of the MANET routing stacks provide for optional routing anyway. So, if you don't want to forward for someone else, don't.

Submission + - What NASA won't tell you about air safety. 6

rabble writes: According to a report out of Washington, DC's WTOP, NASA wants to avoid telling you about how unsafe you are when you fly. According to the article, when an $8.5M safety study of about 24,000 pilots indicated an alarming number of near collisions and runway incidents, NASA refused to release the results. The article quotes one congressman as saying "There is a faint odor about it all." A friend of mine who is a general aviation pilot responded to the article by saying "It's scary but no surprise to those of us who fly."

There is never time to do it right, but always time to do it over.
