The 'killer feature' of SkyDrive/Mesh for me is the ability to synchronise files across all my devices, even if my cloud storage is full. In fact, I can select which files/folders to synchronise into the cloud in the first place, allowing me to manage the capacity I'm using and only back the most critical data up into the cloud.

Goes Google drive have this feature?

As an Australian citizen and having listened to Conroy speak in a number of public forums, my concerns over his filtering scheme have shifted dramatically.

Originally I was concerned that the proposal was what most people still seem to think it is: mandatory filtering at ISP level of a government-defined blacklist.

Conroy has made it clear a number of times that what he is trying to implement is quite different.

There is, and has been for 8 years, an existing process whereby Australians can request classification of a site by the classification board. If the board refuses classification (and there is some debate around the definition of RC, but that's another matter), then the board can issue a take-down notice and the site is added to a black list which is currently distributed to software filter vendors and ISPs to facilitate voluntary filtering.

Conroy is simply proposing that this filtering be made mandatory.

The reason this changes the focus of my concern is that during discussions in public forums, I heard comments from average, non-tech-literate citizens and families, who are supportive of Conroy's proposal because they are concerned about exposure of their children to unwanted material and believe that his proposal will help prevent this.

If we really want to encourage a groundswell of outrage against the proposal, we should focus on just how little content will actually ever be filtered by it. We should highlight how very marginally more 'safe' these families will be from unwanted material.

Some stark statistics might do it: There are x billion pages of content on the internet. Australians each day view x million pages (x% of the total). So far x pages have been submitted for review to the classification board (0.0000x% of those viewed). So far x pages (x% of those submitted) have been banned.

Your child is being protected from 0.00000000000000000000x% of internet content by Conroy's plan, at a cost of $x million, or $x,000 per page. 99.999999999999% of content will remain unfiltered for your children. Sound like a good investment?
