That's right.  It's waiting for a window manager, etc.
to be sent from the other system.

Have a look (both the startx and startxt scripts are
quite short).  You will see the -ac parameter in startxt.
It opens Xvesa to remote traffic.

It sends X output to the Xserver at the specified address 
(and gets input from that Xserver).

Nope.  Just an Xserver on one end and some X executables
on the other.

ping to confirm your connection.

You've got no 192.168.1.7.  You did ifconfigs for
192.168.1.1 and 192.168.1.2

The output from X executables run on that system will
be send to 192.168.1.7

What's the address of that client?  
Unless it's 192.168.1.7 it will receive nothing.

Don't get confused with clients and servers.  
(1) configure your network
(2) startxt on one system
(3) on the other system do:
'   export DISPLAY=address_of_system_running_startxt:0
(4) on the same system as (3) execute:  icewm

You can if you want, but it is not necessary.  You don't
need X running on the system that executes icewm.  It
seems kinda strange running icewm on a system without X, 
but it works.  

Cheers,
