  <description><![CDATA[During the past two attempts to demonstrate our highly distributed
majordemo system we experienced many low level problems that prevented
the demo from going smoothly.  These ranged from machines being off
the network, to agents not being in the right state, to speakers being
unplugged.  It is well known that keeping a complex distributed system
up and running is a difficult task, made even all the more difficult
if many of the components are partially or completely autonomous.

Acting as a record-keeper, this agent tracks a user's context by acquiring information from external sources (e.g., the context brokers in different smart spaces). Acting as an information provider, this agent shares the updated context information about a user with systems that attempt to provide services to the user.
