Agreed, but I think this particular aspect needs a little 
LAD input (*cough*torben*cough*).  :-)

I'm all about Real Time.  :-)

And that's the thing... we use 32-bit FP here because it's 
easier to program and desktop has Lots Of It.  But similar 
algorithms can be adopted to handle S16 data and it'll have 
better performance on a mobile device.

When I deliver a plugin... I want it to be Instant Awesome. 
Not, "Oh... yeah... about that:  your phone sux.  Not 
enough floating point power.  Sorry.  All sales are final."

And this is what I'm wondering... could/should this be 
done with an LV2 extension?
