RE: HP B9180 for digital negatives
Time will tell about the permanence of the HP pigment printers. However, I don't believe there is any doubt at all but that color prints made from the last two generations of Epson printers have the potential, depending on final support, for much better stability than prints made by any other color printing process, historical or contemporary, save three-color carbon and carbro type processes. I have enough color prints from the 2200 hanging around in very bright spots to know that they are very resistant to fading, and you can boil them in water and the color does not change. I would expect at least as much stability from the monochrome prints made with carbon pigmented ink sets. My personal opinion is that they will prove in the long run more stable than any type of silver print, assuming they are printed on the right kind of paper.
As for digital negatives, they appear highly resistant to UV. I have not seen any change in the UV printing density of digital negatives with multiple printings.

Before anyone gets to excited by HP, Canon or new Espon Ink, I'd just like to say that as fast as thing change that last thing you need to do is keep reinventing the wheel. I haven't looked at Wilhelm's site lately, but just because he post that something will last doesn't make it so. I suppose that since you are talking digital negs you are not really after a lasting image, but many will also use those very same ink sets to make prints.

In fact, Ted Harris has called the B9180 an "Epson 2400 killer" because of the performance and price. Will scan the arrays printed by the B9180 and send them when I get a chance.
