Well, zAAP for MVS isn't quite equal to an IFL.

For those of use running z/VM, each IFL is another charagable copy of
z/VM.

And for the LPAR people, as well as the z/VM people, an IFL is another
charge for any software that charges by engine (DB2, Websphere, etc)

I would rather see a zAAP for Linux/390

This is what I was hoping, also.  I stand corrected.

I was really hoping that a zAAP would be a bit more interesting than
just a
co-processor running S/390/zSeries code. I had visions of a processor
that
executed the Java bytecodes directly (or via "millicode" anyway).

The zAAP feature isn't needed for Linux as you can just add another
processor for the same cost as a zAAP.  It saves money on z/OS because
the
maintenance cost go up if you add another regular processor, but not if
you
add a zAAP.
