@fmhwong can you please review the WAD (see link in top comment)?

[NottyCode]

@donbourne I have the following feedback:

1. Can we get a use case defined for the collective scenario described in the admin section.
2. The slide that contains the mapping of context roots doesn't include all the context roots of all the feature web bundles we have. I think we should iterate everything that will be on every context root.
3. Looking at the design (and I know I was involved in the current one so this is as much feedback for me as you) it seems like it would be simpler to just say if there is a virtual host called admin_host map these context roots to it, similar for ops_host. Rather than having to define a virtual host and a variable to do the mapping. I'm not sure how easy this would be to do and I think if we were to go that direction it would need discussion as it could be a breaking change, but it would be a lot simpler and more logical so I'm wondering if it is worth discussing.
