DESCRIPTION:\nInternet is for everyone (RFC 3271)\, and as Vint Cerf says 
 "it won't be if it isn't affordable by all that wish to partake of its ser
 vices’'. Global access to Internet for everybody requires not only the i
 ncrease of the service availability\, but also a dramatic reduction of its
  cost\, especially in geographies and populations with low penetration (e.
 g.\, rural and underserved communities). The Internet\, unlike the acousti
 c space\, is an artificial infrastructure that requires for the magic of c
 ommunication some artificial digital devices. There are different models t
 o achieve this: mobile devices and mobile operators\, telecom providers wi
 th cables or fibre. Different models may be required to serve a widely div
 erse global population. We discuss the case of community networks\, crowds
 ourced networks built by citizens\, that contribute and coordinate their o
 wn network devices to create a shared network infrastructure. These networ
 ks have a governance based on the principles of common-pool resources (E. 
 Ostrom) to preserve the local connectivity as a key resource for the commu
 nity. There are successful examples around the world based on diverse tech
 nologies: optical fibre\, GSM\, but we will focus on wireless mesh network
 s. We will show their characteristics\, and explore several key challenges
 \, solutions and research questions that have to do with affordability\, p
 erformance\, scalability\, resilience\, sustainability\, governance.
