Vail has been available for some time now.
see: WINDOWS HOME SERVER | Microsoft Connect
Is this a new beta version of it?
Edit: I guess not.
Earlier this year the CTP (Community Technology Preview) of Vail was leaked online, and shortly after Microsoft made available a public beta of Vail, but Aurora is a new product which is yet to be seen. ZDNet reports that at Microsoft's TechEd conference in June, Microsoft Server and Tools President Bob Muglia said that Aurora is intended as a "small business appliance", and that it will actually include Active Directory functionality, though the extent of this is unknown yet.
