Not keen on this myself. Puts further unnecessary bend at the head of the spoke, plus it makes a right mess of the outside of the flange if tensioned up properly. I would usually argue that the way pictured would be more stable, as the spokes will be much straighter. If it's stability you're after go for any crossed pattern, preferably 3 cross. Simple.
+1, i think it stresses the outer lip of the flange.
most hubs manufacturers don't warranty it, although i heard about some being replaced free of charge.
If you wanna run radial, first only ever do it on the front. Second, get a forged hub, not machined. Third, less holes = better for radial. With 36h there is less metal between holes so it's easier for spokes to rip out of the flange. I'm planning to run radial on my front (on the bike I just posted) once I get the right hub :)
