OK, thanks. 
My post was also meant as a suggestion to change that  usage
restrictions remark. You can't really mean/want what was written there  ?!
 
Maybe under "educational organizations" you want to include
students or  other non-(directly)-commercial research ?!
Else IMO you should really make  it more clear IMO, since none of
the users met here or otherwhere in internet  qualify as
educational institution - yet you didn't critisize them using  Nauty.
Also, when students leave schools/universities, they will  have
apply for a license or discontinue using Nauty ?
Can you tell how  many permissions you have launched already ?
 
Not that I had some specific application in mind, but 
"Weapons  developement or other primarily military purposes" is also
inprecise.
What  about strategic studies, inproving security of buildings,ships,
airplanes  against terrorism etc. ?
And any positive economic effect leads most likely  to an increase
in military budget as well - you just can't separate these  things.
 
Maybe you mean: ".. which increases the expectation value of
damage due  to military action "  or such.
 
 
 
Most people will (future tense) probably just use nauty to solve
puzzles  in magazines or webpages. But it seems that you don't want to
encourage this,  right ?
Else you would probably provide executables, change
those usage  restrictions, make it more userfriendly
for the less qualified users who know  little about graphs
and can't compile programs. (the vast majority).
