Yes, it is available in the US here: http://www.albumenworks.com/

Not albumen, that is just their name. Like Azo this is also a silver chloride paper, just much slower.

I think it is also available at Retro-Photographic as well.

It needs a UV light source (like old mr.sun) and one usually tones with gold, fixes in plain hypo, although there are other routines. UV lamps are the most consistant, but nothing beats taking a snooze in the sun while your prints are exposing. You use a splitback contact frame so you can check on the progress.
