agree, but then a combination of testing/inspection methods
might do the trick; i've had a look at that analyzer/plagiarism
program by Omid David at http://www.cs.biu.ac.il/~davoudo/
and it works fine (after entering guest press enter and then
enter then names of the c programs if they are in the same dir).
It takes some time (could use a progress indicator) but
for the rest its really good in detecting if a program
is based on another program, as it looks mainly at the
structure of the coding, and not to the naming etc.

Disadvantage is you have to provide the whole code
(with the include statements i presume) but some
people wouldnt object to that i presume if asked
*on beforehand* (before entering a tourn) to
supply it to an independent tester who's promising
to delete the stuff afterwards (at least i wouldnt).
If i would be asked to supply your code in the middle
of a tourn after some vague accusations of some  of
my 'colleague' programmers i would feel insulted (and
it wouldnt surprise me if thats the case with F.R)
best regards,
