I'd like to add that the Pirates should be willing to R/P as well. In the times that I've been stopped in my traders, I conservatively guess that only one out of every five encounters has more to it than "Stop, pay $X (give me cargo) or I'll destroy you, go on your way..."
If you really R/P a trader, you would look at being pirated as the cost of doing business, yeah, it can be a tough encounter (if you don't communicate well, or very fast), but it can be very entertaining as well. As long as the pirates demand is reasonable (based on character level, what they're flying , what system they are in, etc...), it can spice up an evening of quietly going from one end of Sirius to the other.
Yes, the server rules tell us that you must do a minimum of R/P before switching to a pew-pew mode of play, but I think more of an attempt needs to made by the person doing the pirating to engage the player of the trader.
Silently dying when being pirated does your character no real economic good, nor is it good R/P entertainment for either party.
