Thanks Steen. I have not gotten a hold of the manufacturer yet, it is just one man in Texas. I called a few times, but he did not answer and I did not leave a callback number since I am in Iceland. But he only has an online store and it appears two resellers. His website says they are out of stock until mid November, and both the resellers said the same thing.
In any case, I am actually thinking about going for the photobackpacker rpt/kelty p2 bag and system. This is a true backpacker's bag made for large and medium format. In a way, it is probably even more of what I am looking for, as I really don't have a good backpack for my large format kit, nor a good hiking packpack. It would not be as good for travel (a bit big for airlines), but it would likely carry much better on hike and be a better solution for 4x5. But I am definitely still considering the Kiboko! It just does not look like it is even really possible to buy at this time.
