Is it possible to align two laptops and configure them to use DualView technology? Or is this only suitable for LCD's and CRT's?
You can use a program like MaxiVista to share screens across the network. The software will emulate a virtual device on your "primary" computer, and stream the display output across the network. The "secondary" client computer will then display the received result, giving the illusion of dual monitors connected directly to a single computer.
As an alternative, you can use a distributed KVM software like Input Director to share the input between both computers, giving the illusion of using two laptops as dual monitors. However, both laptops will still run independently - this will only allow for you to contol both with a single keyboard/mouse pair.
