In the real Star Wars universe IG-88 took control of an entire manufacturing planet. He modified many droid wireless data feeds so the droids would report to him on command. Almost all of his face to face communications were wireless data feeds.
The validity of this proof depends a lot on your definition of "the real Star Wars universe."
The B1 battle droids of the prequels were controlled by a central computer, so there must be some sort of wireless transfer of operation and communication in play. It is not too far to assume the same of ships. That being said, it would/should be difficult with opposing slicers and encrypted communication. So as long as it was a challenge I don't see an issue with it.

I got that from the Star Wars Bounty Hunters novel. I'm reading books to find more material. I bet R2 could do it, but he was always busy with damage control on the Falcon. (Someone had to do it...)
Very little digital computer work was done for the original Star Wars so its not surprising that computers and hacking didn't play a bigger part. Indeed the computers that controlled model movements were analog, and a Printer was a job title.
Even if computers were in use, its pretty rare to run an action movie based on the exploits of a pile of programmers. Personally I think a movie about a much of pudgy guys sitting in front of the screen is really exciting!

I'm leaning this way as well, and I have said what Happy said on other threads. I feel that the skills required need to be 'rare' to make it appear more balanced in the galaxy.
Even if you go with the most restricted version of Slicing (physical connection), landing a Lambda full of Slicers on an enemy ship would still be an effective attack. This would be well within the Star Wars Universe.
I think star wars works better when you don't have wireless data. I take slicing attacks against a ship as using your ships computers, sensors, and scanners to overload targeted systems on the enemy ships. Overload a relay here, crash a circuit there and eventually the ship stops working.
I like what he's saying in that there are no mechanics in the game for confusing the enemy, set this kinda fits the bill. (The real issue is that Slicing causes strain, and not just setback dice.)
As far as slicing fighters goes:
Sure, why not.
If you crack their encryption that a military channel/network uses to avoid such things.
Hint: In Zahn's The Last Command a group of Republic hackers tries that when Thrawn shows up above Coruscant. They did not succeed. So it should start at Formidable and go up to Impossible.
