I think both Yves and I requested such samples on wg26. So far we had
no news from any vendors.
There is at least a validator for those: see dciodvfy if you want to
get started.

Correct. As per Yves original post, looks like Siemens did it. As per
my email Hamamatsu is working toward this goal. From the top of my
head two others vendors where mentionned on wg26 mailing list, cant
remember the name.

What timeline of what product ? My understanding is that one vendor
should make a first step, then it will 'faire tâche d'huile' on
others.

On the other hand JPEG is very well used over the internet thanks to a
very well known open source implementation... back to the chicken and
egg problem :)
