3 Phase 4 wire in my house would be kind of cool - I would just prefer it to be a lower voltage to ground.
It would be interesting, even helpful for machinery / motors - but more of a "Trivial Thing" [Linked Image]

On the other hand, I can think of several clients, friends and would-be customers who would be foaming at the mouth if they knew of this! [Linked Image]
If these people found out, they'd make a mad dash to France, dragging their Families and belongings with 'em [Linked Image]
[refer to an older thread about "why can't I have a 3 phase 480 volt system at my house", where this issue was humorously debated].
