I'm really excited about this becoming part of the core SBS 2003 product. If you've ever had to manage a database solely through OSQL, you'll really appreciate the
available for all SQL 2005 distributions (even the free SQL Server 2005 Express Edition which is the replacement for MSDE going forward).
(Before anyone asks, we don't have an official stance on whether any of the SBS components will support database mirroring yet.)

You can get a free 180-day trial of SQL Server 2005
(Edit - Express Edition is the core component. Workgroup Edition will only be available in Premium).
