My suggestion was to to execute: receive
(which already pipes netcat output to tar -zx)

So far so good.

No, that is not correct.  The piping stops with nc
(which transmits the data to the remote nc).

This is only necessary if /install/doinst.sh  actually
exists.  Many packages do not have installation scripts.

This is only necessary if the package contains a library.

Unless you modified the receive script to execute doinst.sh
as each package was received.  This could be done by merging
the pkg and receive scripts.

That would depend on whether more than one package had a 
doinst.sh script.  And, even if a doinst.sh were overwritten, 
it might not be fatal.  Some doinst.sh scripts are trivial.

I don't really see what the problem is.  I sometimes move 
packages from one computer to another using send/receive.  
I then install (pkg) the package and delete it.  No sweat.

Sure, edit the script to set a permanent destination.
Or, if you were planning on doing a lot of this stuff,
you could configure links to send .tgz files to that
destination.

netcat only cares about the destination (lois).  It 
doesn't want to know the sender (clark).
