In a new twist, speakeasy, a high-speed internet provider has branched out into helping its customers provide WiFi-shared internet connections.

As far as I know, this is the first company to offer a service to provide the billing and back-end support (email, etc) for customers who are sharing internet via WiFi from a standard DSL connection (or greater).

The company has a good reputation (according to BroadbandReports.com) and offers some nice services, like static IP addresses, etc.
