I am building this right now. I need to move our "global" relay setting from the kind3 list to a list for each feed such that you can have as many Global feeds with different relay sets as you want. 

I was trying to use nostr:nprofile1qqsf03c2gsmx5ef4c9zmxvlew04gdh7u94afnknp33qvv3c94kvwxgspz3mhxue69uhhyetvv9ujuerpd46hxtnfduq35amnwvaz7tmjv4kxz7fwwajhxar9wfhxyarr9e3k7mgprdmhxue69uhksmmyd33x7epwvdhhyctrd3jjuar0dak8x6lmt90's custom feeds, but there is too much going on in that NUD. I don't want to have to filter out custom feeds we don't support right now.
