Abstract

Techniques are provided for use in establishing and maintaining a contacting/communication service and/or network that does not necessarily require the use of dedicated server devices. For example, improved methods and apparatuses are provided that can be used to provide peer-to-peer (P2P) or other like forms of communication in such a manner that users can remain aware of others'"'"' online/offline statuses, search for other users, conduct audio/video talk and chat with others, exchange information, and/or communicate in other ways with one another.
