Using the link that heddheld posted I've found that exporting V4 using the collada export works fine using Daz 3.  The rigging imports in to blender okay.  Unfortunately the Daz 4.5 export messes up the rigging a bit and I haven't been able to get it to work without having a go at re-rigging it.

I'm not sure if Daz 3 is still available though  

I also haven't been able to get a satisfactory result with the Transmaps for the eyebrows and lashes

I may edit this later when I'm more awake. (I've just realised that the medication I'm on has turned me into some of the seven dwarfs.  Dopey, Dozey, Pissy and Windy).
