Well I know DCUO isn't cross platform (the thing that bummed me out about playing it after a while, but pc version of it sucks anyway), I think if down the road they do add "ps3/pc voice chat" to FFXIV they should do it how DCUO does it, theres a general voice chat, which idc about, then theres a guild voice chat, which the leader sets access to who has permission to talk on the voice chat, and everyone in the guild can listen. apply this to ls, you have permission set up by shell leader, and sack holders and have everyone listen in.
