I hate to say this, but this sounds highly tricky. The reason that ccd works
fairly well is that the seeks to different disks are staggered not on
a per-directory or a per-filesystem basis, but on a per-block basis ; each 
file has the potential to span multiple disks. To save the information
on the first disk would imply that that data isn't being striped at the
filesystem level, and wouldn't offer any major advantage over separate 
mount points.

Then again, I may be being naive.
