[ros-users] Out-of-Core Octree and Visualization Library

Very cool. I have some huge point clouds that this could really help
visualization for.

One question: the stack wiki page lists the licenses as BSD, GPL and MIT,
but each of the individual package manifests just lists BSD. I didn't see
any copyright notices in the actual files, so it's unclear which components
are under what license. Could you clear that up?

P.S. I tried to file a ticket for this, but even when logged into KForge, I
was not allowed to create a new ticket following the link on the wiki page.
Also it looks like the main project page is also inaccesible:
http://kforge.ros.org/projects/megatree/ just returns a "URL not found on
this service" error page.
