Actually, what I'm saying is that it would be possible to do without anyone ever downloading content to their computer.

Possible - maybe, Likelihood - about as high as getting struck by lightning while gardening in your bunny pajamas IMO

I have. It works fine without the smart content. The smart content is a pain to redownload, and the system to sort, well don't want to spend weeks sorting it out - that's too much like work. Outside of the smart content/encrypted content, it seems fine with bug fixes and a slight increase in render speed.

What smart content were you redownloading? Do you mean metadata? Metadata should be a fairly small download if that's the case. It has actually been recommended to wait for the RC before attempting to redownload your entire library as there will be a direct bridge from your installed content to DC.

So which questions did you have that were deleted may I ask?
