The current mechanic is "there is only one party decker, who is defined to be Damned Good at what he does. Anything more complicated than a data gathering run will get played out; data gathering runs will be reduced to a single Int+Lore roll. Craft (Hardware) and Craft (Software) are useful for building decks, writing programs, and deconstructing or analyzing either. When in the Matrix, it's VR: use your apropriate stealth/larceny/investigation skills, capped by Craft (Software). Your attributes are replaced by the Performance number of your deck, unless you're an Otaku, in which case you use your normal attributes (yes, punching a computer program does do (Str)B damage to it for Otaku, but emptying a gun into it is Dex+Archery...). A computer with a Performance number of N is a Resources 2+(N/2) expenditure, with whether you round up or down dependent on other features like satellite uplinks, hardened cases, and cool styling. Non-Deckers use Trinity's method, which is to give a computer a general Performance stat, and then a number of Applications, each about as broad as a normal character's skill *specialty*. A rating N program is a rating N expenditure. That covers non-deckers pretty well: you have an avatar/agent, it talks to you, and that's it.
