Last week was the Alpha seeding and there was a promise of a beta this week; here's the quote from the Joost blog posted on 2/7/07 regarding the Mac Alpha release:
Do come back next week for the final proper public beta. And if you
where one of the lucky ones - do sent us feedback. We need to confirm
that it works on a wide enough range of hardware and software.
Anybody know anything about the timeline on this?
