Nope!
WUs no matter whether SETI, Einstein, or whatever, are logged to a specfic machine and address in order to eliminate some forms of cheating that used to go on with Classic. I don't know all the mechanics behind how they do it but they can tell if a WU has been worked on by a machine other than the one it was sent to and it will be rejected. There may be better and more indepth explainations, particularly on the SETI Messageboards where I know this topic has been discussed at great length.
