Copying binary files over a LAN using Rev

First I assume each stack is running in its own execution session on the
respective machines - both stacks are not running under the same copy of
the engine on one machine. If that were true, both stacks would be
running on the same machine, no?
Given the above, I can think of 2 ways.
1) Set up a socket connection between the two stacks and write a TCP
data stream from one to the other. If you do this, it might be a good
idea to base64Encode the data before transferring it. And it would help
the receiving machine know what to expect if line 1 of the data contains
only a number which tells the total number of chars being transferred in
lines 2 to the end of the data. Then the receiving computer can read the
socket for 1 line, and then read for <line-1-number> chars. When the
data has been transferred, the receiving machine can base64Decode it and
put it into url "binfile:<newFilePath>". I believe that should work.
2) Open a socket connection between the two and transfer only a URL.
Then the receiving machine could grab the file by its URL (that sounds
painful!) and copy it over. This assumes the file whose URL was passed
is sitting in a place on the sending machine that is accessible to the
3) I bet there are other ways.
Hope this helps -
