	Hi, i've been lurking here for a while and skimmed over
some of the data that was presented to as plagiarism. I have to say I find
it borderline incredible that all these programs have been copied from
handtalk. Are you *absolutely* positive that what you are seeing are not
due to compiler similarities? (Or reverse training against handtalk?) It
seems to me that the simplest way to do this is just to allow a 3rd party
to just look at the source code for the various programs.. 

	The number of real go programs out there are probably under 10
and the methodologies of them may be relatively similiar.. especially
since everyone seems to store opening moves and other dictionaries.. 

	As someone who bought handtalk, I find the amount of
bad blood between a group of programmers that are so small a bit
disheartening. (whatever happened to the opensource go?)
