Mike,
most engines have their own pressure and temperature sensors in the intakes already - but I guess they are pitot/statics too!.
The A380 has all the engines reporting their parameters to the central system which then sends information back to the other engines as well as the airframe values.
More use might be made of all this data, but certification of any computer system on an aircraft is not like releasing it to normal users. It takes much time and effort to be sure that it is as safe as possible (ALARP) and will not interfere with the safe conduct of the flight.
Mac-OS and Linux would struggle to conform, specialist OSs are needed for safety.
