If it's an experiment, the site he links to doesn't add any details or explain why it's challenging/wacky.
Edit: Actually - the site doesn't go into detail as to the nature of the app he's trying to build, but it sounds like it might be some kind of mobile staffing/placement service, i.e. something built for iPhones. If that's the case, trying to find your co-founder by using your iPhone PRE-application could possibly be used as a wacky little test case to prove the necessity of the app you're looking to build.
