I've been watching those 3ware discussions with interest as well, but I haven't seen any commments on how well they work as JBOD controllers, esp if you get smaller ones with fewer channels and stripe/mirror between controllers. If you pair disks between controllers, then that should limit the downtime, and also improve performance. I've been thinking that getting a pair of the two or four change old 74xx series 3ware controllers and then striping across RAID pairs done between controllers.
