We are doing a complete renovation on an office building and they decided to go with a pretty cool system.
All lighting is controlled by software over the existing network and is expandable to up to 1500 devices. All devices are connected via CAT5 cable with RJ-45 jacks built into devices. For lights that are not going LED, relay packs with RJ-45 jacks are added. All lights are dimmable and switchable and have numerous setups.
Basic summary from the company specs as I'm too tired to word it myself.
All lighting control profiles created in the SensorView software are stored within the Gateway. Utilizing its onboard time clock, the Gateway sends out the settings specified in the profiles to the appropriate downstream devices according to the user defined schedule. Lighting control profiles can also be selected and run on-demand via the Gateways Touch Screen. Additionally, by using the touch screen users can view properties about any downstream nLight device.

I am still early in the install and the customer is not sure how many lights and controls they will utilize so I have a feeling this will be an ongoing process.
