AIM to please.
iChat works with AIM, the largest instant messaging community in the U.S. You and your buddies can be either AIM or .Mac users. Text, audio, and video chat whether your buddies use a Mac or a PC. Sign in with your AIM account, and all your buddies appear in your iChat buddy list.
Of course knowing how dodgy companies can be at times in order to sell products, I wouldn't be surprised if this only means that they can show themselves to you, not a two-way system. Not sure if this is the case, just mere speculation.
