Re: computer-go: Authenticating the identity of a remote go-playing computer program

[Dave Dyer <ddyer@xxxxxxxxxxx>]

"program" is a very difficult thing to nail down.  I can provide
a trivial "program" with a checksum that will never change, but which
can do anything I want by dynamically loading other DLLs, executing 
other programs, using other data files, or opening other communication
channels.  

Packaging a complete set of bits, so it would be dropped into
a freshly installed windoze machine, is really hard.  I agree
with the comment that this requirement would make contests a lot 
simpler to judge by eliminating most of the participants.

Practically speaking, I think going beyond official observers
as authenticators is out of the question.
