I wanted to mention efforts to build internet wide event notifcation. See for
example:
The Evolution of Internet-Scale Event Notification Services: Past, Present, and
Future
http://www.cs.caltech.edu/~adam/isen/wacc/
and
Web Push as an Internet Notification Service
http://keryxsoft.hpl.hp.com/doc/ins.html
and the package called Keyrx
http://keryxsoft.hpl.hp.com/
and
Siena (Scalable Internet Event Notification Architectures) is a research project
aimed at designing and constructing a generic scalable event-notification service.
The technical basis of Siena is an innovative type of network service called
content-based routing.
