Yes, there was. However his statement was very vague, it was not clear
what he really meant. I don't think that anybody ever asked for further
clarification.
I think that somebody did, but I am not sure.
Where was that? Well, we might ask for details, why not? It currently says:
Permission is hereby given for use and/or distribution with the exception

profit or application with nontrivial military significance.
It started with http://trac.sagemath.org/ticket/14110 . I jumped in and
now we kind of have code to generate posets faster. But it can not be
integrated into Sage.
