 Networking configuration can be found in the following places:
- * TopDL: IP address, netmask, MAC address (control interface)
+ * TopDL: IP address, netmask, MAC address, VDE switch/port
  * {{{/var/benito/config/routes/$HOSTNAME}}}: routes
 
-TODO: {{{vde_plug2tap}}}
+Each interface on the experimental network will be assigned a VDE switch and port number. If your platform supports VDE natively, then you're done!
+
+For platforms that do not have VDE support, TAP support is sufficient. {{{vde_plug2tap}}} acts as an adapter between a VDE switch port and a TAP interface. VDE also comes with {{{vde_tunctl}}} which can create TAP interfaces on the fly to be used by other apps.
+
+The following example illustrates how one might do this with QEMU. QEMU has native VDE support, but we'll assume for a moment that we can't use it:
+
+{{{
+#!/bin/sh
+
+SWITCH_SOCKET=$1
+SWITCH_PORT=$2
+
+vde_tunctl tap0
+vde_plug2tap -d -s $SWITCH_SOCKET -p $SWITCH_PORT
+qemu -net nic -net tap,ifname=tap0 fs.img
+}}}
+
+If you don't even have TAP support.. get creative. Chances are if you can talk to a file descriptor pair {{{vde_plug}}} will work for you.
