I like that it allows me to access my file from any computer, which has been helpful in working remotely while at home or traveling! Also being able to share files across multiple computers makes this software extremely useful when collaborating internally as well as externally. The fact that you can't have more than one instance of an application open could be beneficial if there were too much going on within your network/computer system. This would allow other programs not related to work time usage to run without interfering with productivity. We are using NCPM mainly because we need secure remote document sharing between employees who do their job outside of normal office hours (i.e., during nonbusiness hours).
