It looks promising. If I can customize it the way I want I will give it a try.
I like the nested galleries, but from what I see photodeck offers only a pbase.com-style navigation, i.e. you see a thumbnail of the gallery, when you click on it you go deeper into the nested galleries. What I need, is a sidebar navigation that works like a category tree and is expandable/collapsable. For example if you click on parent-gallery "animals" it would expand into child-galleries: "birds, fish, mammals etc." Clicking again on the parent item would collapse the view.

I was planning to build such a site based on Drupal or Joomla during the cold winter evenings, but now obviously photodeck does offer some advantages and would save me time.

My question to jfmphoto is: is it possible to set up gallery navigation as I described (as an expandable/collapsable sidebar with parent/child galleries)? If not, will such an option be implemented later? I supply a niche market and quick navigation for the buyers is essential to me. It is very easy to set up in Drupal or Joomla, but as I said photodeck does have some advantages.
