Yeah, I think this is the main issue.  It can cause two problems:

- The login screen appears on the laptop screen (which is closed)
- New windows or the desktop toolbar appear on the laptop screen (which is closed)

I think the fun will come from systems that don't properly report their lid 
status.  I think this is one of the complaints from the X developers.
