Having recovered from the dot-com crash of the early 2000's, the
Internet now features an abundance of new, innovative technologies and
services. We are witnessing the rapid emergence of a communication and
computing infrastructure that enables the Internet to go mobile.
Indications are that the mobile Internet will be "bigger" than the
conventional Internet.

This talk describes the background, status, and goals of an ongoing
research project and evolving middleware system, called Streamspin,
that supports data management aspects of innovative mobile Internet
services, including push-based and context-aware services. Streamspin
aims to power sites that enable users to create and share services,
and that are capable of delivering services to millions of concurrent
users.

The talk briefly covers two geo-context services that are being
integrated into the system. The first aims to enable users to build
services that rely on the tracking of the continuously changing
positions of populations of mobile-service users. The second aims to
extend the geo-context of a user to include not only the user's
current location, but also the user's (anticipated) destination and
route towards that destination.
