I have often thought that processes should include standard control  
file descriptor instead of argument lists and environmental  
variables.  So each process would have (initially) 2 inputs and 2  
outputs.  I think this is user level streams, but I've never seen it  
done in a shell.  Could standard control also give the process a  
stream of capabilities?  Here's my picture of how this might be  
programmed:  http://web.mac.com/yottzumm/iWeb/Site/Web3D_files/ 
pp2.x3d  The magenta spheres are commands and the cylinders are file  
descriptors.  Color signifies input or output for the file descriptors.

stdcap or stdctl anyone?
