Depends, I guess... Actually, our DMS vendor used to have its licensed coupled to several aspects of the hosts network configuration (MAC, IP address, DNS name), and they dropped this very idea already a bunch of years ago - it's annoying for honest customers, it generates unnecessary maintaineance work, and, most notably, in the age of virtualization it's possibly pointless. We run tomcat nodes that live inside different VMWare ESX (or "Virtual Infrastructure" as they call it by now...) hosts. No matter what actually happens to the physical hardware - the machines inside are likely to "stay the same". You can have the same thing running VMWare Server free of charge on modest x86 hardware and will smoothly make your way 'round any machine-tied licensing mode... > You could also have it "phone home" once a day (or once a week, or > whatever) with an app's internal key value, and if you get two > connections from the same ID value, then you know there are multiple > copies running. No. >From a customers point of view, I simply wouldn't deploy such an application, at least not in the "enterprise" market. Bad enough knowing most desktop software is likely to phone home, the very moment our network monitoring would capture any of these server-based applications establishing unwanted connections to some external site would be end-of-life for this application in our environment. Having an application phone home drastically reduces trust in this very application especially if it is meant to keep track of sensible business information. This IMHO is a way that should be strictly discouraged... just my $0.02 on that...
