Scott Adams (Dilbert) wrote a blog post about how to match people who would like to travel together, instead of packages, a couple of years ago. But the problems, namely trust, are essentially the same.
His idea to connect people with GPS is something you could use. His screening idea's are something you could also incorporate.
To make this an succes I would create a social networking site so that everyone who wants to participate can be publicly hold accountable. If all my personal data is known to you I would think twice before I'd steal a package. A scoring system would bring up the most reliable people to do business with.
