I don't know of any, but my thoughts have always been that keyboards really don't need to be wireless or illuminated (the back-lit keyboards offer more of a bling factor than a practical advantage) unless you're thinking extensive HTPC use...
if you're at a desk the wire really doesn't get in the way and you can always get a small led lamp to light up the keys if you're that much of a recluse - besides, working in such poor light as to justify lit keys is horrible for your eyesight anyways...
