I thought about this and i found that it must be possible to separate the 
instructions for pipelining and the content of the spreadsheet file.
Think of a list local on my host and not saved in the spreadsheet (maybe a 
pulldown menu) in which are the instructions "open a pipe called pipeA with 
parameter /usr/bin/convcal C1:C10"

Then we could use something like A1:A10 = pipeA 
and get the result. No possibility for a trojan to change our parameters from 
pipeA because we even dont save the instruktions of the pipe.

You can think of it as a list of trustet binarys each user can define by 
himself.
