It's not possible to hide location. Anonymity and efficient transport
don't mix. This will become even more so at TBit/s transport rates.

That's no problem, as you can use e.g. mix networks to provide strong
anonymity for those who need at a higher layer.  

The sooner everbody realizes this, the sooner we can move on.
