Have one million devices constantly streaming a random stream of data to each other; when a device wants to communicate with another it just swaps the random stream for the encrypted stream.

Hence a trivial example of low-latency anonymity achieved through using bandwidth.

There isn't enough RF bandwidth and batteries aren't good enough to support this.

>There is no such thing as low latency anonymity.

At this moment. You are devoid of imagination if you can't conceive of this happening at some point in the future. The concept does not contradict physics.

Wardriving?
