Sorry for the delayed response...
The short answer is: not anytime soon, if you are currently waiting on it.
That particular feature is difficult to implement properly. However, we have been working on it and other technologies related to it.
We do get requests for downloadable CDs, but it's not the top priority. The requests usually come from only a few countries, like Canada, with huge import taxes.
I will make another push on that front, but I couldn't tell you right now when it would be available.
