11. A system for delivering dynamic media content to collaborators, the system comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, upon being executed by the computer processor, cause the system to carry out the steps of: providing collaborative event media content, wherein the collaborative event media content further comprises a grammar and a structured document, wherein the grammar is a data structure associating key phrases with presentation actions that facilitates a collaborator navigating the structured document of the collaborative event media content using speech commands; providing data identifying a client's location; storing, in the context server in a data structure comprising a dynamic client context for the client, the data identifying the client's location; detecting an event in dependence upon the dynamic client context, said event being characterized by an event type; identifying one or more collaborators in dependence upon the dynamic client context and the event, the one or more collaborators each being characterized by a collaborator classification; selecting from the structured document a classified structural element in dependence upon the event type and the collaborator classification for each of the one or more collaborators; and transmitting the selected structural element to the collaborator one or more collaborators.

The system of claim 11 wherein: providing to a context server data identifying a client's location further comprises means for querying a router for a physical address of the client; and storing the data identifying the client's location further comprises means for storing the physical address of the client in the dynamic client context for the client.
