Using the /sourcedir inode number sounds right. Be careful not to create too many files in /tempdir (create a hierarchy of subdirs). Filesystems slow way down when they get "too many" files in one dir. But take a good look at a tarpipe before applying 'cp' to such a large set of files.

Yeah, you probably want something like /tempdir/srcfilesystem/NN/NN/NN/NN to handle the issue you mention and recursive copies that cross filesystem boundaries. Besides that tempdir will need to be on the same filesystem as destdir so the hard copy will work, and if destdir has been setup as a multiple filesystem target you'll need to keep a tempdir instance for each destination filesystem. Plenty of corner cases to think about.
