I've known Nate for about 7 years now, he's the head mechanic at my favorite LBS. When he got into building frames I really wanted one, but, my wife was going back to school to get her master's degree so we didn't have the funds for a new bike. So, I waited. She got done with school, got herself a job she likes, and I put in a deposit to get in line, and waited some more.
Well, I'm up now, and the bike is under construction! WOOOT! Fillet brazed steel frame, Ritchey's new 1.125" carbon disc fork, Di2 Ultegra, hydro disc, room for 40's. This will be my anything-that's-not-MTBing bike. Geometry and tubing selection was left up to Nate. It's got a low BB, which he and I both like, with a beefy-ish downtube and CS, with a skinnier/lighter seat tube, top tube, and SS's. As for the actual tubing diameters and thicknesses, I couldn't tell you.
Some pics from Nate's Flickr.
Brake hose and wiring go into the frame on the downtube.

BB is lugged, makes it easier to route the brake hose/wiring internally since it gives you more room to work in. Signature Z cutout, it'll get a mesh screen to keep big stuff out.
