Giving other guilds boarding rights to your airship

[Zephea]

The only way you can get onto another guild's airship is for someone from that guild to be in party with you and someone to have recently created an instance of your guild ship, and then for the guild member to invite that outside onto the airship.

From time to time it would be both easier and nicer to allow access to your ship without people having to be in party with you.

It would be friendly and more community building if you could have a list that you could add friendly guilds to allow them airship boarding rights at any time.

I don't see myself ever using this, but it would be a cool thing to add.

They could monetize it by adding an item in a store, a guild treaty parchment, that would let you forge an alliance with another guild.
