Redesigning the plug...

Excellent, I'd love to go on the Dragon's Den with that one!!!!!!

I love people who have that ability to have a revelation of lateral thinking, but hate smart arses.
Not sure how good the moving pin arrangement would be in "real world" conditions.
An option mains lead even if a fixed pin version C/W adapter.

Changing the live wire to blue and the neutral to red is definitely the way to go.

I worked in an office years ago that had a track running around the wall. You could plug a relatively small plug (like the one in the picture) anywhere along the track enabling you to position kit wherever you wanted. Always thought it would be great in a house.

Very, very clever and well thought out.

There hasn't 'alf been some clever b*stards!

I seem to remember on tomorrows world many years ago a sort of plug that stuck on your wall anywhere and drew power, they demoed it with a hoover I think.

I saw a Gadget show episode where they had electronic domestic devices working without any mains cables or plugs.
Don't know how this would compare with sound though. Probably a non goer ( for now ) but...

I think the mains was being transferred via an electro magnetic field through the room, as in similar to the workings of a transformer?

I remember seeing this - i think it was two halves of a transformer, one half (half a core with one winding) in the wall and the other in the device. The device would then be placed in the right area and the flux in the magnetic core would 'stick' the two halves together, thus energising the unit. Clearly you'd get some loss through the 'wall', however this could be made thinner to minimise the losses.

I've recently wondered whether you could apply a similar principle to charging mobile devices in coffee shops - simply place your 'plug' (as above) on the right area of the table and charge your phone/ipod etc...

Well they are all thinking about it.

Most rechargable electric tooth brushes seem to follow this principle - just wish I had a shaver socket in the en suite so I don't have to plug the damn thing in somewhere else
