FQM has a bunch of system names (over 40k or something). Just get Standard to save on download times. Lots of them are from a Tolkein-esque random name generator, so not everyone likes them, but they are quite alien.
Many are real star names, or from a few sci-fi universes, so it is not all crazy stuff.
A System Names Anthology would be excellent, though it lacks the charm of the DNA acronym.
Edit: Wow, need to update the thread link on DNA page... And I might as well release a new version of it.
