Yeah J, it's true, new DSPs are designed to be much more compiler friendly, 
although even with a compiler successfully humming away, this still leaves the 
business of how the two cores communicate, and one is left with a communication 
structure that takes time to design and implement, and which again, leaves the 
code unportable.

Writing for ARM (ie generic 32-bit CPU with a decent turn of speed) opens up the 
code to run anytime, anyplace, anywhere.
