What do you think of enabling CHERI on AROS, running the whole AROS as a SASOS.
Each memory is protected, enabling Zero Copying as in the old days of Amiga, excepts that is now protected.

Backward compatibility?
Just use a wrapper compiled as a trampoline translating legacy 64bit memory pointers to 128bit capability pointers.

If a legacy app crash, by trying to reach memory outside its boundaries it just crash with a Guru Meditation and does not affect the whole OS.

All new apps can be written using CHERI capability pointers.

Benefits?
Backward compatibility
Memory Protection
Speed of approximately 2,5x MMU?
