thanks for the exhaustive introduction. I would keep ASF out of this project, no need to add a million lines of code to access the CAN peripheral. We can extract the info from the relevant files.
Please leave Atmel studio 6 out of the development process, making the code available through the IDE is what we need in order to get many people to help out, test and use the code.
Let me know if we need to design a can shield.
keija: the library will be developed and made available here https://github.com/arduino-libraries/arduino-due-can join github if you want to be part.
