Google talk: Om Malik has a theory about rumors regarding Google introducing an instant messaging client. If Om is correct, Google will use Jabber technology which will enable its users to have voice conversations with users of AOL IM and Apple’s iChat.

My dream “communications tool” would allow me to use iChat’s awesome IM-based video conferencing feature with someone on a Windows platform (without using a third-party host). Anyone know of any workable hacks in that department?
