A few comments I'd like you to address before we merge this.

First, I'd really like to see the netbrowse section at the very beginning of this document. The document will come to life quicker with the nice picture of of the browser showing a listing of multiple devices.

Additionally, I'd like you to overhaul the whole page to not use the default Qemu MAC address (00-00-00) and instead use something else, e.g., c0-ff-ee or similar that we use elsewhere. Check with J-O for good examples.

Also, a representative example for netbrowse would be to have more than one device in the listing, at least one more, and use a different hostname than the default -- because that's one of the first things an administrator changes. Again, check with J-O for good name examples, we use descriptive names in the tests so should we here in the docs.

Plenty of commits. :-/
Anyhow, I hope it is now in shape for a new review.

[jovatn]

LGTM. Additional documentation on netbrowse can be added later.

Amazing teamwork @axkar and @jovatn, I like it a lot!
