The Jobs board will definatelly be a NIP. There are some clients already have something and I might just integrate with them. 

The local stuff can have both. NIP-29 local relays can certify themselves if their posts are indeed local while just posts that tag a location can be more open to anyone posting on it. 

My only need is to make sure if you post to a location it doesn't show up in your global timeline at the same time, like on: https://github.com/nostr-protocol/nips/pull/1233
