82754 Yahoo! Instant Messenger

Would be interested in an self-installing Instant Messenger program similar to the Yahoo! Messenger. Features should include: sending online/offline instant messages, basic chat rooms, conferences, voice chat, groups, adding and deleting friends from the list, ignore list, set status, place for a banner, search box, etc. We are also especially interested in something similar to Yahoo's IMenvironment - with the different moving (flash?) backgrounds. If that raises the price substantially, quote with and w/o this feature The most important aspect of this project is that it is efficiently programmed so that it doesn't deplete my host's resources.
