Will Acrobat.com support for shared reviews end in Jan 2015?

I just installed Acrobat XI Pro (on Windows 7 Ultimate 64 bit) specifically to take advantage of the shared PDF reviews feature. It seemed like using Acrobat.com to host the review would be the easiest path to take, but the UI is not giving me that option, even when the PDF is opened from my account on Acrobat.com. In my efforts to troubleshoot I read that Adobe is going to discontinue support for Acrobat.com shared PDF reviews on in Jan 2015 - if this is true, I don't want to waste any more time on it (maybe support has already ended?).

My other options are BOX and Google Drive. I know BOX supports WebDav.

I could ask IT to provide a server inside the firewall (although reviewers are not all located inside, nor am I, and it will take forever to get this done).

I've done a variety of searches on Google and the Adobe support site, but don't seem to be finding a forum that answers my questions. Maybe somebody else has gone through this and can point me in the right direction?
