AFAIK Jedives BSP Factory takes a bsp and turns it into a b3d file with a lightmap. The idea being that it doesn't need a bsp license.
You still need to pay the license of the tools you use, but the great thing is that if you use Quark to create your map and ZHLT to compile the BSP file, you don't need any license!!!Oh! And BSP Factory is by far the cheapest of the three, only $15.
