IMHO, I wouldn't call that "integrated".  ssh is an external tool which 
provides a tunnel for the X traffic.  I would consider it integrated if the X 
server itself talked SSH as well as the core X libraries.  X clients would 
connect to <someotherhost>:0 instead of <localhost:10> and the X libraries 
would transparently use the SSH protocol if available.

This would be analogous to a non-SSL aware mail client using stunnel to access 
an SSL imap mailbox.  If the mail client to talk SSL natively to the server 
without anything in between then you could call it integrated.
