Forgive me, cause I've not really been following this, but isn't it
easier to centralise the processing to one point? Why make 20 little
devices
with brains when you can have one device direct each display.. IE Control
PC.
Then the smarts go in the PC, where its cheap and simple to do so,
and the displays just listen for their ID at the top of the data packet. IF
ID = ME display.
From what you described each device will need to be taught what it
should and should not display? Would this be done from the pc? Which means
writing a layer to teach the device.. Which would not be necessary with
what
I described above.
Now maybe as a consequence of the devices being networked, they
would
have lots of smarts anyway to do this processing, so the hardware for that
processing is 'free', but I just thought I'd throw this idea
around.
Not that the hardware is something I'm interested in immediately,
but
I think many have discovered that if we leave these things and come back to
them later, we find they don't match what we THOUGHT they were, and then
everyone loses.
