I saw recently a recommendation of http://www.i2cchip.com/ which sells a 
device that provides an interface from a computer to I2C (which 
apparently is a very common standard in electronics).

As I understood it this should easily be able to handle at least 24 
switches.

I intend to look at it myself this winter :)
