Jeff,
Here is a link to photos of driveshaft damage.

Bill,
I think the girdles support the caps but don't restrain the fragments if the cross or yoke break.
Ant,
Yep, I'm giving some thought to having a driveshaft built with 1350's.
James,
ROFLMAO!!!
So far, the consensus seems to be that if the driveshaft movement is limited, the lighter particles with less centrifugal force shouldn't present much of a threat. At this point, I'm leaning towards using a 1/4 x 2" hoop around each end of the driveshaft, similar to Dean's arrangement here

and then welding a lighter (ie. 14 ga. or so) shield around the top 180° of each hoop, wide enough to extend over the U-joints.
