Yes, but I'm an outlier: I'm a Linux desktop user. (Moonlight has proven to be only moderately passable in my testing, and even then, only in those cases where DRM wasn't a requirement.) But speaking more generally: when I'm at the keyboard of a more popular operating system, I have an aversion to websites that insist I install something to make use of them aside from the web browser I'm already using (and a very, very small selection of add-ons). That's the bias you have to overcome to get my eyes on your web app. Whether those eyes are useful to you is your call. :)
