I've got a project that needs a decent live support chat plugin, but the kicker is that it the chat needs to be accessible from the site owners cell phone. He's hoping that he can respond via text message or facebook messenging etc., so he doesn't have to be in front of a chat console all day long. Any experience with a plugin that does this? It doesn't have to be anything fancy aside from that. Just a way for people to get an instant quote on his site, even when he's on the road.
