Ok, I didn't have the time before for it, but here's a possibility.
Skills:
Computers - A character can do most user operations with it. Someone with a lot of ranks could have a superb Google-fu, for example.
When you take this skill, you must choose one OpSys (i.e: Windows, Linux, OS/X, etc). You can use the Computers skill with that OS and only with that OS, unless you take the Cross-platform feat (see below). Alternatively, a character might use his skill with a huge penalty, and might not use any feat.
At the GM's discretion, some "basic" hacking might be allowed (password retrieval, etc). Anything slightly advanced is covered by feats.
Feats:
Cross-platform: Choose one OS. You can use both your Computers skill and feats with it, at no penalty.
Programmer: You can create programs, from the very basic to the very advanced. Programming takes time, though, but multiple programmers can work together (consider it an Aid Another action). The GM sets a DC, and depending on the difference by which you succeed, needed time is reduced. Multiple tests might be needed.
Codemaster: You take half the time to create a program. Some tinkering might be needed when dealing with multiple-programmer projects.
Suggested prerequisite: Programmer feat.
Hacker: Your all-purpose hacking feat. It lets a character use his Computer skill for, uh, non-legal purposes if needed.
Suggested prerequisite: Programmer feat.
Virus Writer: You can create malicious code. This includes any virus, trojan, spyware, etc. Minor stuff are annoying at best. High end programs make international news headlines.
Suggested prerequisite: Programmer feat.
Virtuoso: Choose a specific use for your Computer skill (Google-fu, writing a virus, building an OS, creating an utility, etc). You gain a +4 bonus for any skill check.
Netiquette: You can "blend in" with the online masses. In other words, use your social skills without penalties. I'm assuming there'd be a penalty for them, but even if not, there might still be room for this feat. This feats could also cover flame wars.
Net Guru: When you speak, they listen. It could be a Reputation bonus, Leadership-like followers, or something else.
Suggested prerequisite: Netiquette feat.
Some other points to consider...
If we take the sci-fi route, we can have some feats straight out of Ghost in the Shell. A
Brainhack feat could allow someone to digitally possess someone, access memories or even rewrite them.
I'm not so sure about Conviction. Maybe an
"I'm feeling lucky" feat that allows you to spend a point to treat the roll as a twenty, but not a natural one?
Some existing feats could be used (I'm thinking of Master Plan). Suggestions?
Think I'm on the right track?
