You did not include this in your suggestion.  So it would be something 
like:

Set up serial network with pppd at both ends, and nullmodem cable.
On receiving computer cd /, type 'receive'
On sending computer type: 'senduntar'  (assuming you are not using busybox 
tar, in which case you would need to tar and then gunzip separately)
The senduntar script would be:
cat $1 |nc lois 33 | tar -zx   ($1?)

On destination computer Ctrl-c to exit receive mode then :

/install/doinst.sh
ldconfig

You would need to do this separately for each package otherwise the 
doinst.sh would overwrite the previous one so cat *.tgz would not be safe 
to use, right?

This should install the package to lois without also leaving a copy of it 
on lois, I hope.

It looks like the nc method can also be used to write a script 
'sendfile' that will send a single file without having to answer the 
question about the address of the receiving computer (leave out the tar 
pipe part), assuuming the receiving computer is always lois and the sender 
clark.

This does not sound very simple but we may try it some day.

I think netcat would be simpler. Let me know if my script is correct.
