I honestly don't see this as being a reliable addon. At any time, if one of the two people that this addon links through goes offline, the entire link is severed. With very big guilds, this also has the potential of taking up a lot of bandwidth, which Blizzard wouldn't be very happy with and could lead to the addon being blacklisted. This also would allow cross-faction communication, which is against ToS. While RealID chat itself does do this, it's not at the scale this addon can be configured to perform.
