If I understand it correctly - If you are using it academically or in free software you can use it. If you are using it commercially you can pay a reasonable license fee and use it.
Sounds like a better solution than most; what am I missing?
Honestly, the worst part of CGAL licensing is figuring out which parts actually require the commercial license, since most of the simpler structures in CGAL can be used freely in a commercial product.
I haven't looked for years, but as I recall very little was LGPL other than the core, and the rest was licensed by module. Even if you just licensed the whole thing it wasn't particularly expensive.
