As I understand it, Mark's employer (university) would not let him
release the work as GPL-compatible. Otherwise the module would have
replaced r.los in the main GRASS source distribution years ago, and
their institution would have been cited many many times from it, but
oh well, he tried a number of times to convince them.

Considering universities like Johns Hopkins and Columbia literally
generate billions of dollars licensing IP (typically bio-med), and
how underfunded most educational institutions are, you can understand
a bit why the suits at other universities around the world have a
hard time seeing very far past the $ signs for anything and everything.
