Actually, there are cases when a user or an administrator might need to
remotely access the current running desktop session. Kulbir already
mentioned one (something I myself have often wished ... access to my IM
client from whatever workstation I'm on without interrupting
connection). In such cases, I like the idea that the screensaver stops
and allows the activity on the desktop to show (if I were the user, I
wouldn't want anyone accessing my machine without my knowing it if I was
sitting in front of it with the screen locked). However, I wouldn't want
the keyboard or mouse to be active, either (still requiring an unlock).

If that were to be a feature request (or even a security review),
against what component should it be reported to? Does screensaver even
support just input-locking?
