Copying files to multiple comp's on a lan

Hi again,

I got the win32all as Mark suggested and everything works like a charm now!

Just one more question:
Is it possible to

cmd_string = "copy %s %s" % ("\\Machine1\C\temp\foo.txt",

when I am sitting and issuing the command from Machine0?
I'd like to design the script so that it copies the file to/from multiple
comps at one time, not just from the source to all the other machines one at
a time seperately, but more like:

Step 1:
copy from comp0 to comp1

copy from comp0 to comp2
copy from comp1 to comp3

copy from comp0 to comp4
copy from comp1 to comp5
copy from comp2 to comp6
copy from comp3 to comp7

and so on and so on...

where comp0 would be the initial source

Is this possible at all? Doing it this way would make better use of the
network, its switched, so collisions should be a problem, although the
traffic will be immense if I'm disting a 700 MB file.

All for now,
