This has been considered before and we certainly would like to develop it and produce products based on it (we're engineers and tech heads, after all). At some point in the future, who knows. But right now it is cost prohibitive. While integrating wireless connection into our products would open many options for expansion accessories and make for an easier installation in some cases, it would also add quite a bit of cost to the base product and open up a whole new set of support and installation issues to deal with. In the end we have to consider if there would be enough people willing to buy at the price we'd have to sell at in order to make the investment in this make sense. Also, many (most?) would still want the cheaper wired only option, which means we'd have to produce wired only and dual wireless/wired models.
So far we are skeptical.
There would certainly be some that would benefit from it and some would be willing to spend more for the feature, but until we either decide to make a gamble on it or land a high volume production deal that would benefit from the feature (or in which it is a requirement) it isn't likely to come up.
Some other ideas, such as LCD backlighting, are within the realm of possibility within the price levels and volume levels we're dealing with.
