I've just came up with a super-original-idea-do-not-steal, that I can't be arsed writing-up on a monetized blog before telling websites like Hackaday.
It's a variation on the 'Solderfree Breadboard from IDE connectors' idea (http://www.instructables.com/id/Bread-Board-from-IDE-Cables/ et.al), where the 50-way IDE header sockets have the adjacent pins of the bottom half soldered together.
It gives you multiple access points to GPIO signals which is really handy too.
