I can see the advantage in being able to set collision in the editor. If you want collision off now it is as simple as changing Physics on? to 'no' in the editor.
You can also script collision off but that requires the entity to be dynamic which might not be desirable once static lightmapping is introduced.
A funny thing happened on the way to the forum...
