i can think of two options:

= - you could go for an all Plan 9 distributed solution. this will be the eas= iest to roll out and maintain in my opinion (security, administration, main= tenance, etc). i have used this setup with over a dozen 9pi cpu's (tftp= booting from a 386-based auth+fs) collecting bluetooth data (via usb) and = logging it on the fs. =C2=A0it worked well; the collector is a simple rc sc= ript that reads files served by the bluetooth fs and writes the data to the= (imported) filesystem; it all uses 9P, of course.

- you could build a 9P network on top of heterogeneous OS environments , b= ut things get unnecessarily messy. you have to deal with authentication, = =C2=A0log forwarding or u9fs, non-standard ways of talking to USB, or seria= l and needing to build your own 9P file server for each, etc.

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

Some q= uestions:

* Would it be better to use a RaspberryP= i Plan 9 CPU image rather than a terminal image? The only interface I will = need from the RaspberryPi to the Arduino is TTL serial
* Eventual= ly I would create another RaspberryPi, running Linux using 9mount, to displ= ay various statistics and data about the system. I'd be writing the int= erpreter 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&q= uot; 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 t= his system setup? Please note, I am doing this to get a handle on 9P.

Many thanks!

Shane.
