In case you didn't get one, Office Live pre-beta emails were sent out at the end of last week. Promising "a free Web site with your own domain name, free hosting, online business applications, e-mail and more" along with easy access to "your company e-mail, customer and project information from almost any Internet-connected computer" this is one Live service that is definitely not targeted at the home consumer.
You can still sign up for the beta program at the Office Live homepage though as always, not every applicant will be offered a place on the beta.
The beta is open to US residents only, and requires Windows XP and Microsoft Office 2000 or higher.
