you'll find horizontal dropouts on TT bikes where you want to "tuck" the rear wheel into the seat tube. Minimum clearance required for race is 2mm (was it or something like that??). Cervelo P2's and Cervelo P3's are setup that way (I think). These aren't the only ones.

Getting pretty bad with details...
