Since simply having a USB-fed monitor would not be bleeding edge enough for you, DisplayLink has updated its Virtual Graphics Card software to support the Windows Vista Aero 3D interface. The update, version 4.3, is available to all DisplayLink-based systems, including USB graphics adapters, docking stations and monitors. DisplayLink claims it's the first implementation of Aero in a network display technology, and since you can plug in up to six displays with VGC, certain maths would say that adds up to a whole bunch of Aero.
