So you might have heard about EQ's /pizza command. Here is a link to a commentary:
Everquest pizza. The last paragraph states:
"That basic idea -- sending messages from the game world out to the real world -- strikes me as having enormous potential. Various gamers have ported their email to games, so they get alerted whenever an important real-world communique arrives. Indeed, if as game economist Edward Castronova argues, a greater and greater chunk of people are going to spend their lives inside game worlds -- where they effectively generate thousands of dollars of real-world value every year, usually at tasks far more interesting than their "real" jobs -- then it behooves game designers to allow them to manage and monitor their real lives more easily from inside games."
