Is R2D2 the most advanced hacker Droid in the galaxy?

Clarification: in ROTJ, R2 was in the middle of hacking the door when he caught a blaster bolt that caused what appeared to be total system failure. So, he started hacking the door, but didn’t succeed. You’ll recall that right after that, Han said, “Well, I suppose I can hotwire this thing,” and on his first attempt he actually activated a second set of doors, sealing the shield generator even more. Just the sort of thing that can happen without R2.

And in Ep. 4, my read on it was that R2 showed Luke just enough of the message to intrigue him, then passed on (through C3P0) the idea that “the restraining bolt might be interfering with the rest of the message”. This was, I think, a ploy on R2’s part to goad Luke into removing the bolt so that R2 could sneak away later and look for Kenobi. I suspect that the bolt wasn’t actually interfering with the message at all; R2 just said that to further his escape.

Bothans don’t really make a lot of sense. According to Wookiepedia, Bothans are some kind of furry bipedal goat creatures (link). One would think that the Empire, known for its xenophobia, would have no problem keeping infamous spying goat people away from their vital information and installations.

Because most everyone who matters already speaks *his *language? The more tech-minded citizens of the FarFarAway Galaxy seem to be fairly conversant in Binary - certainly R2’s owners like Anakin, Luke and Cade seem to understand actual content not just tone.
