Nice idea. It would certainly make prospector a more viable career.
I can see one argument against it though. NQ generally wants the game to encourage teamwork, so that players (well, at least the majority of them) have to find their place in a society with people depending on each other. These trade-able data items may make it too easy for a prospector to operate as a "lone wolf" and just sell to whomever will pay the best price. Without them a prospector will have to either be part of a society or establish a certain degree of trust from his/her customers, which would require some more engaging interaction than through a market-unit.
Still a good idea though. I'm not completely against it.
