To answer the bloggers question: It could be a bit of both. Remember, R2-D2's memory was never altered, as See Threepio's was. It's possible that since the Republic became the Empire that they used many of the same codes, etc. as they had in the past (they figured very few people would attempt to work against the Empire). Furthermore, R2 wasn't just any droid, but he belonged to a Senator of the Republic.
OR it could be that plans to the Death Star Princess Leia had given R2-D2 was so thorough as to include getting into the computers.
At any rate, we now know "Old Ben" wasn't just a desert hermit and that the Jedi were pretty technologically savvy.
