I was quizzing a vendor who wrote the code for their product to use a zIIP 
and was assured nothing special from IBM was required. Which meant anyone 
could write enclave SRB code and set the bit requesting a zIIP engine and it 
would be honored, providing a zIIP was available and not overloaded.

So as a curiosity question - if you can answer - is access to a zIIP really 
being controlled or is lack of knowledge preventing the masses from rewriting 
code so everyone buys as few GP engines as they can and matching zIIPs to 
lower ISV costs?

I am not planning on using one in any code I write, just wondering if only the 
larger ISV's can afford to 'use' the API.
