These things don't seem to be too complex for lawyers and accountants to
keep track of, but I suspect their complexity will be incentive for a
growing number of artistically expressive people to step outside the
industrial entertainment realm and take shelter within the closed loop of
an exclusively copyleft community -- where everything anybody does with a
pool of internally generated works is simply available for re-use by
anybody who plays the same licensing game with their "derivative" work.
But I understand that all the variations of licensing will intermingle (and
sometimes clash) outside of that community.
