Hello Mr Yukata,

Thank for your patch, it's running (I just had to fix a small buffer 
overlay problem).
As a contribution I will write a small extention to the manual to 
explain how to use the X11 proxy (for the only command I know about 'x') 
and how to use it being a NAL firewall.

Do you plan to add this patch to CVS ? Or is it recommanded I keep it so 
that I can apply it on the next release ?

regards
