Well for one I think without giving a hash value for the data to be downloaded, say a known good torrent, this can only result in tears for the end user. Adobe pirate releases, notorious for being infected.

But to the point of your comment I would be wary of just considering it downloading. If, again using the bittorrent file transfer idea, you download a copy you could very well be considered to be making available the intellectual property for illegal obtainment. I personally wouldn't want to be stating "support said it was OK" if my ISP or an IP protection firm's lawyers take action. Since Adobe has worked with ISPs to monitor and issue complaints I wouldn't put this out of the realm of possibility.
