This would be way cool, reasonably easy, but probably slow.

You could for instance make an alien spaceship
& have part of it swing out to reveal stairs & the inside of the ship
like I recently wanted to do.

Problems might crop up trying to make patches fit together, since 
there are disks, bezier, triangles, polygons etc. all with mathematically
different edge shapes.

One possible syntax would be to use "patchmesh" instead of "mesh"
 ie
patchmesh{
	FINITEPATCHOBJECT...
}
