I saw somewhere that you can now link Jabber or AIM with RadioUserland. It can be used to post to a Weblog via a chat client. What about a tool that would send the transcript of a finished conversation to an archive directory on a Blog? Here is an example:
John and James are discussing through instant messaging about a current project. At the end of the conversation, James either type a "special keyword" of press a button and the whole transcript is sent to his copy of Radio Userland through XML-RPC. Once in Radio it is formatted and upstreamed to the project "chat archive" directory for everybody to see. An anchor could be posted in front of each sentence to allow somebody else to link to an exact point in the conversation.
One more for the "to do" list...
