Hi Sean,


I think you and I must both be forgetting the same amount of material every 
six years, because I didn't remember it either :-)

This does point to a need to be able to something like ProxyPipeline or PipeableOSProcess
simply and with less confusion, and maybe with a class name that is not so wierd
that nobody could ever remember it.
