Hi 9fans,

I wish to have a 9P based sensor and actuator reporting system for an
aquaponics setup I am designing.

I was going to use a RaspberryPi running Plan 9, an "A la mode" for the
interface to the Arduino shield, and a Cooking Hacks Open Aquarium/ Open
Garden shield (so I would need two RaspberryPi's). On the control side of
things, I would have my MacBook access the namespace via Mac9P.

Some questions:

* Would it be better to use a RaspberryPi Plan 9 CPU image rather than a
terminal image? The only interface I will need from the RaspberryPi to the
Arduino is TTL serial
* Eventually I would create another RaspberryPi, running Linux using
9mount, to display various statistics and data about the system. I'd be
writing the interpreter for the information from the Open Aquarium/ Open
Garden shields in Python. With what I have described, all I would need to
do is "open" the TTL serial stream file from each of the RPis and read out
the data, am I correct?
* Does anyone have any constructive thoughts on this system setup? Please
note, I am doing this to get a handle on 9P.

Many thanks!

Shane.
