world on menu missing modem access alone

I have been using croquet beta Americo course 1, however I've been 
corresponding on some physics and not "playing croquet".

I got an idea for an experiment :
Putting a powerbook aluminum on a wifi network of mine (be it an 
external airport express or the internal wifi) allowed me to demonstrate 
a looking glass jump on my single powerbook aluminum and with single 
image file with only 20 lines of squeak code, 10 lines per primative 
virtual world.

I did not enable a wifi LAN but only had internet access.

This doesn't allow rabbit jump with internet WAN single image, though it 
knows my temporary location in postcard as xml :
<joinme><routerAddress>12.74.217.235:50783</routerAddress><routerId>638dc7215db1ae4dec9d490a21b0ed5b</routerId><routerName>DMU 
Navigator World 
(235.dallas-19rh15rt.tx.dial-access.att.net)</routerName><vpn>mainEntry</vpn></joinme>

I know, from trustworthy sources, that were I to send that through e 
mail or chat mechanism, someone might jump to me (I think I have to have 
the hoster world up, somehow, just from its name). The HosterMaster 
class method generates a world without menus about where you are.

Oh, to be somewhat clearer without forcing readers to go through the 
course, here are 20 lines :

hm:= HosterMaster new openInWorld .
win1:= SystemWindow new.
lf1:= LayoutFrame new.
lf1 leftFraction:0.
lf1 rightFraction:1.
lf1 topFraction:0.
lf1 bottomFraction:1.
win1 setLabel: 'close the 2nd halo first HOSTER be pacient in the load'.
win1 addMorph: hm fullFrame:lf1.
win1 openInWorldExtent: 600@600.

nm:= NavigatorMaster new openInWorld .
win2:= SystemWindow new.
lf2:= LayoutFrame new.
lf2 leftFraction:0.
lf2 rightFraction:1.
lf2 topFraction:0.
lf2 bottomFraction:1.
win2 setLabel: 'close the 2nd halo first NAVIGATOR'.
win2 addMorph: nm fullFrame:lf2.
