Agree. My patch don't drop the dynamic way to use TUN/TAP! Or it has a 
bug in it.

I don't want to stop support of others virtual switch or whatever new 
interfaces! I just tell about VDE because I like it. Now ok, you can arg 
that you can make everything with a "-tun-fd" option, but this requier a 
wrapper for every use and this is I think the best way to confuse users.

Ok.
