I definitely approve of this idea, being able to share a house with another player if you decide or even one large "linkshell" type housing would be even better. Hopefully they'll implement something like that along with Free Companies, personal "hangout" areas for each Free Company that would let you decorate a small room for each member. But back on the subject of shared homes if they ever implement a marriage system into the game it'd work perfectly with this option. As long as they don't go overboard and make it into like a mini-Sims game within FFXIV...
