It occured to me that I could either do the "strobes 'n' stands" thing, or I could mount a 400WS Quantum flash on my camera. That would definitely up the room light, and would save a good bit of setup and teardown time.
You could mount 2,400 w/s strobes to your camera and it will not achieve the effect I think you are referring to. You'll just have to expose your subject standing a few feet in front of you at about f 128.

The inverse square law complicates things.

You basically have two subjects in mind here. One is the action or person/people in front of your camera that you are focusing on. They require a certain amount of light.
The second "subject" is the background or environment you are wishing to add light to.
When you walk into a reception situation you have to figure out your optimal shooting positions for the people in relation to the environment. This is where your on camera flash or hand held flash is going to come into play. THEN you consider the room and figure out how to place a light to take care of that.
- Are you wanting to bounce a light into the room?
- Are you wanting to cross light your subject or back light them?
- Are you wanting to light the background independently from the subject so your background light doesn't spill on to the subject?
So simply adding more light to your camera isn't going to take care of the two main subjects. All it will do is make your back hurt and blind your subjects.
When we are shooting receptions we regularly have a flash in one hand and a flash on a stand. Just to give you an idea of how little light you can get buy with... Marc and I both can make it through an entire wedding on one set of AA batteries with our hand held flashes.
I really can't give specifics to how exactly the lights are set up because each venue is different and one light on a stand can be used in several different ways depending on where you are standing in relation to that light.
I can say that a good place to start is having one flash on camera (or hand held) and while you are shooting the dance floor, have another flash either bouncing into the ceiling or lighting the background of your images without spilling the light onto the dance floor. This will begin to give you an idea of what the light is doing in your specific venue. You'll be able to judge the amount of power you need coming from that second light and what sort of ratio you want to set it at compared to your hand held flash.
Don't try this out at a wedding though because it can be maddening and frustrating if you don't have a handle on it. You'll be dorking with your lights and missing shots you need to get. Get access to some sort of large room that would be similar to a reception hall and have a subject go with you and spend and hour or two with it before you pull this at a wedding.
Just remember that you are lighting two subjects at once and each subject has different challenges or needs yet they have to work together visually.
