I have been looking at designing an ‘eLua Stamp’
and started using the Luminary Micro parts but then decided to wait for some of
the ports to bigger chips (AVR32)

We're working on all of the
below :) We'll start to design an open source "eLua stamp" as soon as
we can, everything else that you mentioned is already in line with eLua's
goals.
Best,

Independently of the debate about which chip to use, we can
learn from the
Basic Stamp and the Arduino "business model":
1. Sell (via commercial partners) a hardware module containing the SOAC chip
already boot-loaded with the Lua system so users can move directly to
application development without additional equipment (such as programmers or
debuggers).
2. This module needs to adapt the surface-mount high-density chips to
breakouts which can be soldered or connected by hobbyists, experimentalists
or prototype builders.
3. End user does not care about the chip - select one (or a few members of a
family) and concentrate on getting that to market at low cost.
4. Make the hardware design open-source as well as the software.
5. Include networking and USB - there has to be a tangible benefit for the
slightly higher price-point.
That's how I see it anyway!

Look at the STM32 range from ST. Not /so/ cheap, but very cheerful,
wide range of parts. 32 bit ARM Thumb 2 core, USB, CAN, RTC,
timers, serial ports, ADCs, etc etc etc. Available with Flash/RAM sizes
ranging from 16kb/6kB up to 512kB/64kB. Also well supported by GCC.
I have a few STM32 development boards here; I should try to get Lua
going on them; it should work great.
