Is ADE for web truly on the way, or will it always require a tool download?

I'm looking for something similar to Flash Paper but with DRM protection and support for standard file types like epub.  Requiring a download for my users (The ADE program as it is now) is not an option.  I'm excited by the second half of this ADE FAQ reply pasted below, but is this something truly in the works or just a fuzzy promise?
Are Digital Editions capabilities available within the web browser, such as Reader and Flash Player?
Not at the present time. The focus is to support an immersive, content-centric experience with eBooks and other digital publications. The lack of distracting web browser "chrome" offers a simpler, more engaging user experience. However, we recognize that certain workflows will benefit from native file document-viewing capabilities embedded within a larger browser-based web application, and we are evaluating options and timing for delivering this capability to content publishers


You are not going to get an answer to this, other than it isn't available now.  Outside of occasional slips from our marketing folks, our pre-announcements tend to be limited to "it is now in a public beta".  Also any announcements would be on either the blog, developer site or official product site (or all three).
