However the question is whether one needs to invoke clause 6 at
all. Clauses 3 and 4 allow the development of "modified versions"
without any forced distribution (but with a patch clause). Normally,
extending a library with a main program counts as modifications - at
least that's the case in the theory of GPL, and it is my impression
that this interpretation rests on solid legal ground.

Viewed in that light, QPL 6 gives an *additional* permission to
develop application programs and distribute them under *another*
free(ish) license than the QPL, provided that one submits to forced
distribution. Without this permission the license would still pass
DFSG #3 (due to the GPL-like clauses 3 and 4), so it should not be
considered non-free just because it is there.

Henning Makholm                     "However, the fact that the utterance by
                           Epimenides of that false sentence could imply the
           existence of some Cretan who is not a liar is rather unsettling."
