Theorycrafted for a bit.
A) The forces on the rim during braking would be the same, regardless of lacing pattern (I think)
B) As the wheel continues rotating forward (resisting the deceleration at the disc rotor) a J-bend spoke would rotate slightly in the hub flange, causing more serious wear on the flange holes.
C) B) works in reverse, as well. During accelerations, the hub will spin up before the rim and there will be some rotation at the J-bend. Maybe a huge spoke tension could fix this though.
D) If the hub flange were beefy enough, radial disc could be doable? Could someone invent a radial straight pull hub that would be able to handle this better?

Update - So I (finally!) got my wheel back yesterday and I was able to catch up the group mid-ride. Did a 25k ride with lots of climbs and everything is fine! 
Mechanic said the spoke snapped close to the nipple. He was able to reuse it & installed a new spoke. Plus, I got fresh sealant in there since they needed to remove the tire to get the nipple. All that for a 20$ bill.
That would be a hard thing to do on a SLR disc wheel...
