I am very interested in this product and will likely buy it but i have a couple of questions. I wanted to see if this package can prevent certain types of sharing 1 - can it prevent sharing of logins and passwords by many users? 2 - Can it prevent someone from downloading a file (pdf or word doc) and then posting it or reselling it on another site? I would like to be able to post a file and have someone print it when they want to but that is all. 3 - Can it prevent someone from opening a file and printing it hundreds of times to resell it?
