Inode signatures are fast, MD5 is slow. You have to read the whole file
to determinate the md5 sum, and that's exactly what you want to prevent
using inode sigs.
I think on FAT ctime & filenames should be enough to detect corruption.
I don't know how tla should detect corruption on NFS though. Actually I
don't think there's a right way to it. Either you don't do it at all,
which is bad (since you work without a safety net), or you do it with
md5 (or something similar), which is bad (since it kills performance).
