One possibly better solution would be to create some kind of CRC of the
xattr data (MD4/MD5/whatever) and send just that in the file list for
each file.  This would allow you to figure out when to update the xattr
data, but the protocol would need to be modified to send the xattr data
during the file-update phase (and possibly to allow the reciever to
request just an xattr update without doing a file update).
