Thats actually encouraging, thanks Sriesch! Also well worth thinking about. My books have done fairly well, and I have only had 2 customers who weren't able to use them and that was 'exactly' for the reason you stated (and both Daz users).. 

Hence why I'm here looking for options. 

I think to offer my models as a scene subset seems like a great idea, and thank you for your input.
