Milwaukee 2 1/4 hp 2 7/8" plunge
Porter Cable 3 1/4hp = 3" plunge
Etc.
Get a up-cut spiral bit and you are good to go. I would still do it in a few steps maybe 1/2" to 3/4" per pass depending on the material. Just make a good jig so you can good repeatable passes.
Maybe like this (one of my fav's)http://lumberjocks.com/HungryTermite/blog/13593
Or just Google "router mortise jig" and look at the "images" for a few thousand other ideas ;-)

The router collet extension sold by MLCS mentioned above looks good. BUT t=
he wrench flats on the extension piece are about 1 inch or so around. If y=
ou were trying to extend a 1/2" spiral bit that is 4" long for example, the=
wrench flats would prevent you from using the extra length the extension p=
iece provides. It kind of only works as an extension if you are routing a =
hole that is 1-1.25-1.5 inches diameter or greater. So the wrench flats ca=
n fit into the hole you routed. Not sure this extension piece is really ve=
ry useful in the real world. Most holes I rout are 1/2" or less. Rarely r=
out holes over 1 inch in diameter.
I have the Porter Cable 7539 router mentioned above. Great router. 3" plu=
nge. 5 speeds. Soft start. 1/2" and 1/4" collets available.
