As one who is using the md5 process, it's not that much more complicated: Drag files into xACT, md5 them, drag to desktop, md5 and compare. The only thing that takes really long is md5ing the files on the 722, since their FW interface is not yet speed-optimized. For 6 GB of files, the md5 step took 10-15 minutes on my friend's Powerbook.
It's still faster than a real-time transfer, and I can live with the extra time it takes to *KNOW* I have a perfect transfer.
