Hi,

First, please fix your clock/smtp, either you sent this mail in november 2010, 
and I just received it.. or it was sent with the wrong timestamp. I almost 
missed it!

Anyways, the basic needs for the connection to work is : to have UDP 
connectivity...
In the logs that you posted, I see that the laptop never receives anything, not 
even from the STUN server during candidate discovery. So either your wireless 
network blocks all UDP packets, or it simply blocks anything that isn't 
whitelisted. Obviously, if you can't access the net, or can't do UDP, it's not 
going to work.

About the tutorial, that's great news, yes, please send me that, it would be 
nice to see what you got so far!
How are you writing it? docbook or something? maybe set up a public git server 
for the documentation ?

Hope that helps,
Youness.
