Sorry about that. What I meant was is it possible to limit the copy/paste buffer size to xx number of characters on a Linux desktop. Along the lines of allowing users access to say copy and paste a website address but not something like a whole paragraph or document.
Basically, boils down to security lockdown so that users cannot copy/paste large amounts of text from say internal corporate documents but can do things like copy/paste webpage addresses, email addresses, etc.
Does that make more sense?
