In the middle of all this, please keep in mind that Dawn is likely to be used in Carrara, Vue, Lightwave, C4D, modo, Maya, 3DS Max, and a host of other 3D studios. And to those users, the added complications to details surrounding the Poser/DS difference could well make it harder to adapt as an export. Don't sacrifice quality, but keep it as simple as possible for the sake of those who operate outside the duality.
