But I doubt we'll see something like this anytime soon.
Canon had a patent few months ago for a 2.4ghz based flash system

No more worrying about line-of-sight or fiddling with accessory triggers.
Thanks for the hint, I totally
missed that post.
Let's hope they'll release it rather sooner than later.
