Yes, this would be very useful, as the others have said. If it could handle other file types such as CR2 and HR2 as well, that would be even better. There are some things you can do in Poser which result in embedded geometry in the CR2, apparently, and this is a pain which is well worth fixing. There are other reasons to have an external OBJ as well; it makes remapping easier; it means a prop can be used in other apps such as Bryce or Vue d'Esprit; etc. etc...
