Re: Deletion of Virtual Display Devices

Jim,

 Just to throw another angle at it.  I once had a situation at a client 
where there was a scripted hacking attempt.  (Don't worry, I discussed 
with the network guy about how they got past the firewall.)  By keeping 
the virtual device list "clean" I was easily able to detect that there 
were far more than there should have been.

I don’t see the value in removing virtual devices in most environments, the exception being where specific authority to devices is set due to security requirements.  Then again in those environments we don’t automatically create them either.
