We've developed a custom ESP module called the Acorn which we will also make available separately, and we are pursuing (with RF engineers to help us get it right) FCC modular and CE approval.
We've also developed a free Spark API compatible cloud for it, and a real time dashboard system.
Of course its all open source - so I'm sure we'll be contributing heavily to the Arduino IDE project and the ESP codebase in general (we've spent the last 6+ months on our Arduino IDE compatibility for it)
Thanks to everyone here for a great forum (and to the admin for running this) - I wish it had been here when I started on this project - but since it started it's been great to see it grow and I've found many answers here as well!
