Technically, tun doesn't provide eth0 for the host either. In fact, the
kernel documentation says you need to have eth0 first, or else you cant use
tuntap (that may no longer be true though, remember this is from the offical
kernel docs :). tuntap provides a tun0/tap0 device in the host and an eth0
device in the guest. user net should provide an eth0 as well, but it won't
add anything to the host.

If eth0 doesn't show, that may be due to lack of hardware support. Be sure
your kernel has support for the ne2k-pci module.

user net isn't just for internet access .. the guest can still access the LAN
or the WAN/intranet .. they just can't initiate a talk to it.
