one way i would imagine how you could get 4 player playstation move game's with a Playstation move and sub controller. with this added that would be 14 bluetooth connection's on the PS3 at one time.

Now as for the developer's making use of that ability is something all together, though the PS3 works with generic USB hub's anyway, it would be nice having this many connection's for a Multi type of tap for the PS3 move motion controller so you could have the 4 player's that can each have a playstation move plus the Sub controller at the same time all wireless.

No I have much doubt that the developer's would support such a set up because the PS3 only come's with 7, though this would fix such a limitation. i doubt very much they would make use of it. but still I think it would open up some uses.
