Babaoriley: Perhaps Rainer has posted a response from POET about that and I missed it, but I don't think I did.

No, I didn't post any answer yet, because I don't have one. My note should have been passed on "to the scientist in the company to comment on that and update where necessary".

Unfortunately the company or should I say the has been extremely unresponsive lately. At this time, I have three specific technical questions open with them waiting for an reply.

However, it won't surprise me if my questions are not at the top of their priority list, and I can live with that.
