I'd like to see virtual host switches (VMware ESXi and MS Hyper-V) added to the 'on' topics. These switches share a lot of logic with their physical cousins - and need to interface with them - but do have their own flavor. On-topicness (is that a word?) should be limited to the *switch configuration* on the host, not including other host configuration items.
