Create Interactive Twitter Feed for WordPress

This is project is for the creation of a Wordpress plug-in that resembles with Twitter functionality of [login to view URL] (not the video). ? It should create a chat session that multiple people can login to post, displaying all mentions related to a specific keyword. This project is not for resale and is to be used on one specific website, so, if there is a 3rd party solution available that I am not aware of, I am happy to pay you to implement it.
