Stationary installations which would serve up PublicDomain works up over wireless and cat5 connections with a few key sites offering printing services. These can act as repeaternodes or as machines hanging off already installed nodes.
Low cost and low maintainence computers with as few moving parts would be the best solution though that may not always be what can be afforded.
The main focus of these installations would be to serve up PublicDomain works. Secondary benefits include increased PTP wireless coverage, a potential place of community-centric information, and more.
