Quote - a) (in what way) are the Poser channels Alt_Diffuse and Alt_Specular supported? Because IMO that's where most of the conversion routines go nuts.

They are scanned completely and all the relevant information converted. Yes, it's not easy but it was imperative for me that the conversion would take in account the data in those inputs. As you said, most of the action happens there and so there's the need to preserve the data that shader writers have created. 

Quote - b) can we - especially as a community, with freebies etc - build a Poser Materials Library that i) looks well in firefly and ii) works will in Lux after conversion, so we can use FireFly as a kind of previewer while building scenes? That is: can we establish specs for such materials? So we can have mats that serve both engines, instead of mat libs for each separately.

Absolutely. One of Reality's main features is its Material Editor. With it you can take full advantage of Lux's physics-based materials and edit them as much as you want. You can then save the shaders to disk and share them via a free service called ACSEL Share. ACSEL stands for "Automatic Customs ShadEr Loader" and it loads the customs shaders automatically whenever you add the assiciated figure or object to your scene. ACSEL Share is  a free service that allows Reality users to share and install shaders for Reality. Access to ACSEL Share is built inside Reality.

Quote - BTW: R3 looks really good, I'm a fan already.

Thank you very much!
