Is it securely: `hostname`:10 ?

This certainly happens on Linux/XFree - I think it actually uses a 
local socket rather than shmem, but the communication method is not the 
same as for other IP addresses.

To make life more complicated, a machine that gets its IP address from 
DHCP or similar may have an entry in hosts for its machine name but 
with 127.0.0.1 (saves rewriting hosts on each address acquisition).

It would be good if openssh could handle this brokenness effectively.
