The thought I had was that the ethertap interface is much more versitile
than a slip interface.  You can send much more arbitrary network data, more
protocols, etc.  Also, it allows you to setup bridging fairly trivially on
the host such that eth0 is bridged to tap0 which would let you have the uml
hosts appearing on the same outer network as the host, just as vmware does
bridging (though it does it through a slightly different manner).
