With respect, in my view, it's not trivial. As you point out, it's not 
actually allowed everywhere. Unless you are some kind of local townie who 
knows all the bylaws, you'd need to call your local building/permitting 
office to be sure.  I've lived in several places where it was definitely 
not allowed. In (al)most all places, you also need a permit to do the 
work, even if the PtB let you do it as an unlicensed hobbyist.  Also, any 
given rinky-dink home electrical panel box isn't always going to support 
30A breakers, might be out of room, or might not magically grant you the 
service-line current you may require (or in the case of 3-phase, the third 
phase you are going to need). You'll also need to find a route to get the 
proper sized wire in to the walls to feed the L6-30 or whatever 
receptacles you need, and install the outlets. That's real physical work 
in my book and may non-trivially eat your weekend.

The other thing that's not trivial is that if you make a mistake, you will 
likely either: 1. Die.  2. Burn down your house. 3. Ruin some expensive 
and rare gear. 

To me, that all sounds like a helluva pain and != trivial. Then again, I'm 
a software guy. What do I know? :-P
