You point the real question: why it has been impossible to get accepted 
any patch that fixed this. I has proposed one myself and I get no 
comment at all. I see similar effort from others and obviousely there 
failed almost the same way. No getting any valuable comment about why a 
idea proposed by many peopoles is not applyed make this subject very hard.

I hope that we can resolve this subject, because in my point of view, 
using a existing "tun" is far more simpler than create one the way quemu 
do; and this open a lot of new uses in terme of the network managment of 
the quemu instance. The very first one for me is to allow only root to 
setup a DHCP server and to assign "tuns" interfaces to the users that 
needs it, so there don't even have to think about the network setup, 
ther just boot into quemu an OS with a DHCP client.

Any comment this time ?
