A chat room would do fine, although i doubt that a chat system would be defeating the purpose of a forum, people who have computer problems will choose to post in a new thread because it will last, but if it was in a chat room, then it would only be for an instant ... something like a simple Java chat room wouldn't hurt at all ... i mean, rather than having threads all over the place talking about random topics or subject, we would have a clean and simple chat room where everybody can participate ...
