== Introduction ==

Community is an important part of a peer to peer experience, and a unified user

are XML documents adhering to a user profile schema referenced below.

User profile information is exchanged at strategic points in network communications,
using packet types defined in subsequent sections.

== Profile Challenge and Response/Delivery ==

Requesting a user profile from another user involves a challenge and response
transaction. The challenge step allows the initiator to provide a random token for the
respondent to sign with a digital signature and return, verifying its identity. This
allows a distributed identity safeguard, which is under development.
