“A hybrid model is becoming more popular. Users can operate software applications in the offline mode. In the online mode, a user connects to a authority center through the network to access extended time limits.” [sic] (Huang et al. 2014)

“software vendors must also mature in their ability to improve the user experience, fix security holes, and provide new features.” (Ferrante, 2006)

“Generally, the machine host name offers the weakest node locking, since a user can change the name at any time, while the dongle offers the most stringent. Other node-locking mechanisms are the Ethernet MAC (media access control) address, the Internet Protocol address, and disk serial number.” (Ferrante, 2006)

“Customers typically pay annually, which means they might often invest several years of capital at one time in a single solution. The subscription model is based on the premise that both users and software vendors benefit from auto- matic continuous updating.” (Ferrante, 2006)

“subscription-based licensing provides a steady stream of income to the software vendor, while enabling the cus- tomer to spread payments over a longer period.” (Ferrante, 2006)

“Both subscription- and utility-based licensing underline the need for reliable data on license use as well as for software to help interpret that data.”(Ferrante, 2006)

“Vendors must think beyond protecting their intellectual property and extend solutions to protect users from unnecessarily jump- ing through hoops,” (Ferrante, 2006)

“A standard framework and toolset would lighten every- one’s load. Software vendors would not have to create as many licensing implementations from scratch, and IS departments would be spending fewer resources managing individual licensing systems.” (Ferrante, 2006)
