NAME

CHI::Driver::Ping - Cache data in the Ether.

SYNOPSIS

  use CHI;

  $< == 0 or exec 'sudo', $0, @ARGV; # sending ICMPs requires root priv

  system 'sysctl', '-w', 'net.ipv4.icmp_ratelimit=100000';

  my $cache = CHI->new( driver => 'Ping', ip => 74.125.73.105 ); # google IP

DESCRIPTION

Tap into the Ether. Optimize for CPU or storage? Fuck that.

If you thought the Cloud was awesome, just wait until you try storing your data in the Ether.

Inspired by Delay Line Memory, http://en.wikipedia.org/wiki/Delay_line_memory, this modules stores data by transmitting it through a medium known to have a delay and waiting for it to come back again, whereupon it both returns it and retransmits it out again.

It seems rather pointless and silly to bother with spinning metal oxide covered platters or billions of tiny capacitors when data can be stored in the air between the Earth and sattelites, in ordinary copper wire, and in easy to extrude lengths of glass fiber.
