@ mitnick29, merci de l'input. Ton raisonnement s'approche du notre, avec comme r?sultat des chiffres similaires...
@ junglejay, I agree, but I'm currently not at liberty to discuss some details, hence my intentionnaly being vague. I'm hoping to get an all clear in a matter of days, I'll give plenty of details then, but for all intents and purposes, let's talk about a device with the specs in the OP, since that's what on the shelves at major retailers. Imagine simply that you've added Z-Wave or Zigbee connectivity to it.
@ watou, thanks for noticing

In fact, this whole IP thing has gotten so out of hands, that this project's first expense account is... legal. Yep, not R & D, not GUI or cloud or hardware or even salaries... Nope, it's legal. If you're American, start paying attention to the battle that's started because it won't end before Congress rethinks the IP laws. I happily blame Apple and Google for creating the climate we live in today, that allowed such abberations as Intellectual Ventures to exist...
So yeah, to answer your question, we're hoping that while these two go at it, we'll be able to perform a micro-progress in technology... but let's not get our hopes too high shall we ?
