Well I had figured that in the Space Future hacking would actually be a pretty major thing in bounty hunting - tracking people by their presence in local wireless networks, hacking their transactions, security cameras etc...Think about how easy it is for people to track you NOW using digital stuff and then extend that even further.. To say nothing of there's a whole spaceship there you really don't want someone else hacking. 

As for Harken: He IS a human, he just swapped his meat body for a robotic one. If that's too sci-fi an idea I guess I could modify him to be just a heavily-bionic organic, like a rabid transhumanist, but I dunno... Would that be acceptable? Why the no-robots rule? What level of sci fi are we talking here for your setting? Is there really no such thing as robotics or advanced cybernetics? We're traveling between solar systems here, so we must have some kind of FTL travel, right? And it's for petty bounty hunting so that means FTL stuff must be pretty commonplace, so the overall tech level must be really high. I'm just unclear on what level of tech-ness is acceptable. And if you're opposed to quite advanced tech, I'd have to throw him out and go for one of the other slots? Pilot, muscle or engineer, right? Must admit, not many of those really appeal to me..
