What if you had a kind of particle, that had different qualities(or properties) that could be programmed irrespective of each other? If you then developed the software to read each different property, you would end up with a simultaneous multi-use system.

Along the same lines: you could have two movies running on the same screen. The first would use the normal spectrum, to which our eyes are accustomed and the second could use e.g. infrared, which could be watched, using a special filter(spectacles).

Never mind me! I´m probably talking out of my earhole again. Ralphie does get some strange ideas sometimes.
