Well, i find that a qemu_switch would be more convient as you could set up
the network at boot time (like i do with vde now).

There is only one host. And if u don't use tuntap, then no host configuration
is required (remember slirpvde?).

Guests have to be configured anyways (tho slirpvde includes a dhcp server).

VDE provides this already. Of course, a user-net based solution for qemu guest
networks could do a few things that slirpvde can't (like -redir support). It is
definitely worth trying for.

For the most part tho, it's just duplicating functionality that we already have.
