no no no.. it's simply, since the OP posited a math solution, md5. ship the size of file + hash, compute file on the other side. All files can be moved anywhere regardless of the size of the file in a single packet. The solution is left as an exercise for the reader.
Bah, you should include the solution, it's so trivial. Generate all possible files and then do an index lookup on the MD5. It's a little CPU heavy, but darn simple to code. You can even stop when you get a match, which turns out to be a HUGE optimization. :) -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
