So, I was watching the trailer again, and in response to a similar comment (that the DUST tech was a rehash/breaking of the existing capsuleer tech), someone responded with an interesting point:
To summarize, they said that one disadvantage that DUSTies will have vs. capsuleers is that while a capsuleer, while licensed, can purchase as many clones as he has the funds for and thus theoretically go on forever with no outside interactivity, the DUSTies will be entirely and completely reliant on their patrons - capsuleers, primarily, but the various nations for NPCs - for the acquisition of new clones.
To be clear, I am not at all sure this is actual PF. In terms of game mechanics design, this brings up some serious issues - will people be able to purchase clones from NPCs, and the handwavium applied to say that the NPCs are actually doing it? - but if it is accurate, then it sets a fairly serious limit in place for the DUSTies: They're only as immortal as their patrons care to make them.
Given the utter chaos the unfettered capsuleers have unleashed on the cluster, that'd seem to me to be damn good policy from an IC perspective for keeping the DUSTies in line.
