The load command only supports regular files. If you want to read data
from a socket or a fifo I think you will have to use C-style I/O:

http://www.gnu.org/software/octave/doc/interpreter/C_002dStyle-I_002fO-Functions.html

And when creating the fifo as you did:

> octave:1> mkfifo( "testfifo", 666 )
> ans = 0
> octave:2> ls -l
> ...
> p-w---x--T 1 oba   oba      0 Jun  5 12:02 testfifo

Octave does not convert the second argument from octal, so try

  octave> mkfifo ("testfifo", base2dec ("666", 8))

to at least create the fifo with the correct file permissions that you intended.

  octave> ls -l testfifo
