The easiest way is for each router to have it's own axis to be able to move up and down independently, but it's more complicated to build. Buscht's looks like they all move together. Not sure how he does it, because it seems like the other bits would get in the way. With independent axis', you just move each one independently. You would probably use fixture offsets to locate the second (and/or third) router(s). Sorry, but I don't know the g-codes offhand.
Personally, although I haven't tried them yet, I'd go with the Craftsman collets like Bill. Get a good Porter-Cable Router, and set up all your bits in the Craftsman collets, and tool changes can be very quick. But, if you need unattended tool changes, dual routers would be the way to go. (If you have the room for them)
