A single Lighting Device (Switch) element can be chosen as the "Switch" for multiple Switch Systems. However, a Switch System cannot be connected to two separate switches. So currently, three-way switches are not possible in Revit, and are commonly addressed by adding Shared Parameters to them in order to label them correctly. Searching through this forum should net you some more details on this work-around.
