Low resale value?  You mean low cost?  I think you are saying you want 
this cheap enough that you won't care so much if it is damaged or 
destroyed, right?

But if there are easier ways nowadays to have a back port that can add either Blu-Tooth or USB access with most of the smarts on the side of the plug that plugs into the widget, that'd be good too.

So the serial port is not for interfacing to things being read or 
controlled, it is for configuration?

I've never implemented a free standing Forth on a processor like the MP430, I don't know how much SRAM and FRAM would be reasonable (shockingly I didn't see any application note at TI that address the issue, either). Physical size wouldn't be an issue, no matter how small the chip the device would have to be made big enough to bolt down.

It's not very often anyone says they want little in the MCU.  The cost 
of the MSP430 with 16 kB of FRAM is around $2 at 1000 each.  Can you 
care about saving another $0.25 by using the 8 kB version?  If you 
aren't shipping 100k units this small price delta just is not important.

Ok, so size, weight and power are not issues.  Is price the only 
constraint?  Any idea how large your app would be?
