Rolling Wi-Fi oases as cures for boredom

Wi-RAN is moving beyond simply connecting users to the internet on Mass Transit, whether they be buses or trains to becoming community servers, providing stored content and local apps to people with time to kill, which is typically a ride of more than 45 minutes.  The local server part is necessary, because the mobile broadband experience is deficient, and will be for the business plannable future. We're looking for new and at existing apps to connect travelers on the same vehicle with each other, on both an asynchronous discovery basis "Who else on this bus wants to play cards?", and knitting the regulars together, in a book clubbish kind of way.  If you think you have an app that suits this model, let us know about it via plunkman at cedx dot com.
