Microsoft is tinkering with a technology called Stuff I've Seen that will pull results from the Web along with one's own computer and its network. (Microsoft claims this won't make personal files viewable by the public.) Google's Internet Explorer toolbar tracks the sites users surf and relays the addresses back to headquarters.
Axis will be included as part of current toolbar bundling deals with Firefox and Internet Explorer that last year resulted in Yahoo shipping over 80 million browsers.
