yes but in that it seems its VISA that excludes mnos, VISa becomes the trustlet owner, but the same my-business/your business barrier would seem to apply. Their is the notion that the trustlet must get into/out of the TZ for each and every run, but I'm inclined to think VISa or the mil or anybody else will consider such information, information that the event even occurred to be proprietary and not enforceable at a per event level.
edit: more clearly, loading the device with the trustlet bears a fee, the actual running of the app (migration of the app to TZ), an entirely untethered intradevice event, bears no fee. The frequency or even the occurance of such an event being proprietary to the trustlet author/owner.
