Below is a comment about X-Windows security sent to me 
by a person with a lot of experience in computer security:
===========
Dave,

X-Windows has been known to be insecure for some time. That is to
say it can be hacked.

Now you could get the code and change the sockets that are used or
require authentication of every communication. But this would slow it down.
You might also have "virtual" x-windows where you use 127.0.0.x as the 
endpoint and refuse to allow non-local connections.
============
Would implementing virtual x-windows as this person describes above
solve the X-Windows security problem on OpenBSD?

Thanks
Dave Feustel
