I'm arguing that whether you have access to those devices should depend 
on who you are, not where you are, just like every other unix operation 
checks pre-established settings for user and group values against 
pre-established settings on every file and device when opening them.  It 
shouldn't be determined by whether you are able to touch a certain 
keyboard.
