also most Autodesk software needs local admin to run right or at least the older ver of it did.
AutoCAD 2013 (and 2012, and at least a few more versions back) run fine without admin rights. It helps to have write permissions opened up on various AutoCad folders (Program Files\AutoDesk, ProgramData\Autodesk, etc.) to allow for customization, but the application will run fine. Admin rights are only needed at the time of initial installation.
My understanding was that they still did only hashing if they had the file already, and would pick random bytes of the file to hash to ensure it *really* was the file they have in their backend storage. I'll have to test tonight with a download.
It will still do the upload de-dupe within your own account. So if you upload a file, and then rename it and upload another copy, that will still happen mostly instantly. If you're going to test it out, make sure to use two separate Dropbox accounts.
One snag - it is impossible to differentiate between legal backup and illegal warez. Both would be in the form of an ISO (or other disc image) and are indistinguishable. Now what do you say to the person who has a huge game collection and all his discs backed up legitimately?
Yep...that's why I said "if you can detect pirated games". The burden is on Sony to figure out how to do that, without punishing their customers or taking away access to legitimately purchased hardware/software (including the legally allowed backup copy)
