This is wrong, if you used "ssh -X" then DISPLAY is already set (by ssh) and it has a different value, usually localhost:10.0 for the first connection. The idea is that ssh will tunnel the X connection through itself (thus localhost) and it uses a configurable display number (the 10.0). The reason it works from some computers and not from others is that even if the X server exists at myipaddress:0.0 it could be blocked by any firewall between computers; the ssh tunnel is the way to avoid being blocked.
