Hi Spencer,

Thank you very much for your feedback!

The Section 5 updated:

I've updated the first sentence, it's now saying:

"This document discusses the most common scenarios of connecting an
   enterprise network to multiple ISPs using an address space assigned
   by an ISP and how the approach proposed in the "ietf-rtgwg-
   enterprise-pa-multihoming" draft could be applied in those scenarios."

(https://tools.ietf.org/html/draft-ietf-v6ops-conditional-ras-06)

Do you think it's more clear now?

Oops, sorry, did not think that the word 'area' is *so* overloaded..;) Fixed!

Fixed:

Good point ;) I've added quotation marks around 'silver bullet' to
indicate it's a the figure of speech.

Fixed.
