Add the "SITE MD5 filename" facility.
This allows you to determine if the file on the other side is the same
as the one you have without transferring the entire file to compare.
Needless to say, if the server end lies to you this check doesn't work,
but on the other hand, if it lies to you about the files checksum,
what can you trust from it ?
