> I think the problem might be how to provide in-wall cabling that's to code for 220V That's no problem, standard romex nm-b is rated up to 600V. The only real difficulty in doing that in most US homes is that it's all or nothing. You'd have to upgrade all receptacles on the circuit to 240V. Depending on when your home was built, the kitchen might well have several circuits for the wall receptacles (even just one circuit per receptacle, not terribly uncommon in my area), which makes converting one of the circuits to 240V pretty trivial. Given how many appliances these days use switching power supplies capable of a wide range of voltage, I wouldn't be totally surprised if it was possible to wire an entire house with nothing but 6-15 or 6-20 receptacles and not have too much difficulty sourcing compatible appliances.

Most kitchen appliances require the right voltage. They normally have a heater or motor driven direct from the AC voltage. Most devices you'd use outside the kitchen usually will work on any voltage - with notable exceptions being vacuum cleaners, washing machines and fan heaters.

  For sure you'd want to be careful. My Kitchenaid stand mixer would certainly be unhappy if it were plugged into a 240V outlet, but Kitchenaid makes a 240V version that I could replace it with. A lot of work, but technically doable. Probably about as likely as wiring up DC receptacles throughout the house. Zero.

I believe that US code requires a dedicated circuit for all 240v outlets. Only 120V outlets can be chained. The only people who use 240v outlets are planing on using all the power it can provide, if they want a second outlet they want a second circuit as well. Check with your local codes of course. Even if the local codes allow it, your building inspector may not.
