A particular sector that when visited sends individual players to a unique instance of a station that is "your own" and subsequently customizable. At a minimum it is a storage place for the player that maybe is built by the player with higher cost for more additions. This allows for the possibility of you being able to give other players access to your station by permission...

Upon writing this I realize this could be applied in a way that reduces the amount of data that needs to be stored. Make the station automatically for successfully created guilds as a whole. As the guild grows the station's storage and features grows. Only guild members can access the station.. a non-guilded player only sees an empty sector or a generalized station. This also opens an easy door for player created markets within guilds.

-1. Stations are already somewhere in VOs future but your basically saying once one is made its a safe haven, which is not okay, the " player market within guilds" is a stretch, and I'm not 100% sure what you mean by it. Most guildies sell to other players or guild members already, whoever will buy more or by preference

Why would we need a sanctuary or safe haven in VO? Serco and especially Itani space are quite safe.

I don't buy doing this all in the name of "player trading" If you trade you meet up with a guy at a spot and trade items. I think its nice we don't have trade "contracts" meaning items are instantly swapped avoiding bad player intervention but I go off topic hehehe.
