VNPL 1.1 is slightly reworded to make it clear that proprietary software interacting with Vitastor and providing some kind of service to end users isn't a "Proxy Program" if it's not specially designed to be used with Vitastor. For example, Windows OS running in a virtual machine stored in a Vitastor cluster clearly isn't.
