The Amiga can access the Sonnet memory 'directly' (about as fast as CHIP mem on a 060). The Sonnet cannot access the Amiga memory (or hardware) directly (could set up an address (MMU) exception to catch em and transfer it to the 68k CPU; very slow). Message passing PPC-> 68k can be achieved by a 68k process/message port located in Sonnet Memory, I think. Both CPU's can interrupt each other.
