Interesting idea that phase flipper, particularly as it can be done for each outlet, which is critical. If half of your equipment has its AC in the wrong phase, there's no much point in flipping all of them so that the other half then has it on the wrong phase.
What I think someone should come up with is an AC filter that has replaceable snap in modules. I find the real problem is the compatibility of the chokes with each individual piece of equipment. Imagine one that has different snap in modules where one can choose the perfect value choke, filtering, and even phase for each piece of equipment.
It's not like chokes and caps are all that expensive. They could send the unit with 6 outlets and 10 different modules.
Sorry, a bit off topic.
