Technically, we could ask Helmut to distribute source for them, since
they are derivative works.  Of course, as the sole author, he is free to
license them however he sees fit, but then he'd need to release them
with a libpano under a different license, which he never did AFAIK. 
That's just a technicality, though.  We are all so indebted to his hard
work that it's frankly not worth pursuing.  I for one hope he isn't
hesitating to release them based on IPIX threats.
