The really interesting point here is that companies are PAYING to use
the StingRay tool kit to begin with. It's not free.
Then test has to pay for add-on licenses so WinRunner can work with
it? This looks like a bad business decision all around.
Stingray should have insisted if they open their source code WinRunner
users should get the add-on for it for FREE.
Having to pay more to use it is NOT an incentive for anyone to want to
use StingRay products.
This has been an issue for my company.

Just my opinion (not my companies).
