GPRS and Special theory of relativity

While "special theory of relativity" may provide one many wild thoughts, I just happened to think about an interesting thing. We all know GPRS. GPRS is done through a packet switched communication over circuit switched networks. As circuit switched networks are inefficient, GPRS technology uses blank time slots where circuit swithched network is not being utilised. And hence more bandwidth is available to one to communicate.
I just happened to think, if someday even if we dont make a time machine ( but some how we partially make it ie. we are able to bring time dimension also in to our realms of communication) then in GPRS communication we could also use slots those are free in nights even if we wanted to communicate in day. We could use time slots of future. Then world might be fighting over these furture time slots as it fights over oil today ( Think USA and India have a Indo-US time slot division deal, By which Indian companies can buy time slots of US, there are discussions in world economic forum where IBSA is against G8 countries because these countries have very high rates for their communication time slots, or UN peace summit has communication time slots in its agenda). Imagine the amount of bandwidth one can achieve that way.
Well, Bandwidth itself is a wonderful term. It comes essentially from frequency domain representation of a signal( which if you see is in time domain only (controversial thought though, some communication engineers will not agree)), so this future usage of Badwidth will add another dimension to the Bandwidth as we say it today.
Let me explain it a bit, let us say I send 2 images to my friend, one goes in current time and one goes in future time, but even if the image will come in future time, My friend sees it now and says "Dude you look great". (It seems crazy, and that is what is).
Imagine, the speeds that we will be able to achieve, Imagine the amount of data that we could send in minutes, imagine other impacts of same thing, Hackers if peep into your system, they will devastate you in seconds. People will do many wonderful things if time machines become possible, but I am free to have my own thoughts. :-D
