I'm surprised it hasn't had a mention on the forums yet - the rumours of a Google Browser.

The BBC covers the issue failrly well here:

I started collecting links to soruces on the issue a few weeks ago:

it's been doing the rounds in some of the other forums checkout the whois on gbrowser.com

Hey Brian ... not too many links in your list there. Let me help you out with my thoughts (http://forums.searchenginewatch.com/showthread.php?t=1836) on the new browser. Then there is the now infamous missing Bugzilla report (http://www.webstractions.com/news/2004/09/mozilla-based-google-browser-very.html).

The one that has me wondering is this SEO Chat post (http://forums.seochat.com/t15915/s.html) by ericwfrost in which he eludes to a Beta download for the new Google Browser. Downloads are apparently by invite only.
