You are right that there is no derailleur hanger on the San Jose or the Raleigh One Way, which i assume is the bike the previous poster referenced. As such, you don't have the option of running geared later, like you would on a CrossCheck, or an older touring bike. Upon closer inspection, the Casseroll takes caliper brakes, not canti. It'll handle bigger tires than most road bikes (up to 35mm), but is not really a CX frame. Maybe it's more of a Surly Pacer clone? It does look like a nice frame.

If the OP's goal in having horizontal dropouts is to have the ability to single speed and gear the same frame, the CrossCheck/80s touring bike is where it's at. One option that hasn't been mentioned is the sliding dropouts in the Voodoo Wazoo.
