I don't say no real-time Linux can, but I rather trust a netwrk of PICs
with the hard real-time and / or sub-10seconds timing of things, and use
the Linux board for things that are soft real-time and > 1 second. Just
a matter of economy, this is a one-off rather low-budget project, so no
experiments or techniques that I (and my customer) are not already
familiar with.

And what would be my gain if I did otherwise? The network of PICs is
required anyway, and I need a main computer for the ethernet interface
and to serve a few web pages (which are the user interface). Linux on
the main computer is readily available, costs next to nothing, and can
run the software that I developed on my PC Linux box. In fact I will use
Python, so it can run the software that I developed on my Wintel machine
:)
