Glenn,

There is an example program for the MPI parallel processing library called
monte.c

You can find this on the web, search for MPI. Sorry cannot remember the url
right now.

Anyway the program given uses random numbers to find the value of pi, this
is a REAL world example of transmitting random data.

The Short of it is that the program can be modified to gain a large
efficiency boost if the random numbers are generated locally instead of
remotely and transmitted. ie the engineer is supposed to recongise that
transmitting megabytes of random data over a network is STUPID when they can
be generated locally at each node.

Just a REAL example involving the information content of random numbers.
Look it up yourself.

Therefore my statement stands that once you know something is random you
don't bother sending it.

If you cannot find it and want to verify this then let me know and I'll
email you the complete code.

How about you post a REAL example where the random numbers have to be
transmitted.
