We should have an NPC who has ports available like the portal NPC and the ports are based on which paintings with ports you have placed in your guild hall.
Like the Painting: Haunting Laughter from the Bristlebane Anniversary quest that will port you to Shard's Landing? Just not so many random clicks
I really like this idea, and would probably use housing more thoroughly if there were more useful (as opposed to cosmetic only) items with which to decorate. Magic paintings, with a visual link to a destination, seem like a "why hasn't this large-scale happened to paintings already" kind of idea. Edit: This is the kind of thing on which I would happily spend station cash.
I honestly, would be happy with just getting a Port Keyring. I mean that is the one thing that I would actually use and buy keyring slots for.
