I don't have a home studio but own one SB-800 and already have some experience on using it remotely when shooting a party at a "Skihütte".
I placed the SB-800 on a table, hold it up in my left hand or put it on a cupboard. The ceiling was not of the best neutral color so in some cases I just aimed the flash strait at the room.
I was quite satisfied with the resulting "crossfire" of the built-in flash of my D80 and the SB-800, although sometimes my own person was in the way of the remote flash, casting a nasty shadow
But still: the addition of some wider room illumination made for some much better balanced pics than just shooting with one flash from the camera position.
If you mount this system to a tripod and use an umbrella to reflect the light I'm sure you would get very
nice results, esp. if you consider buying a couple of SB-800s.
If you don't have money like hay, just start with one and convince yourself of the astonishing quality of the SB-800. You can also use the SB-600 as slaves
