This might be just a suggestion. Why don't you make one run of lights and have one computer. Then you could record playbacks to only affect the lights in one room. For instance lights 1-5 are room one and lights 6-10 are room two.
If you are looking to control these rooms on your wifi network may I suggest you look at this website. It will allow you to control each room with your iPad or iPhone wirelessly.
