Yep, until we all get fiber-quality uploading, we will never have true cloud performance for design files. 9 megabits a second means it would take about 51 minutes to upload that on a decent cable connection. And that's still way too long. A fibre 250/250 would be done in a minute and a half.

Personally I want streaming documents and live changes. At least some kind of collaboration features to go with my "cloud" ;-)

They won't though.

Look at Business Catalyst. That's hardly a coder or creative friendly platform. There (seems to be - it may have changed) no way to reliably archive your sites unless you spend a grand to become partner, and the templating system is so arbitrary and chaotic as to make it almost impossible (at the very least, impractical) to move a site from BC to another platform (I tried to make a general purpose PHP framework to run a basic site, stitch together the templates, mock up the 'webapps' which are not at all webapps and gave up in frustration.) And look at Muse, the WYSIWYG editor they want people to use with Business Catalyst -- it 'compiles' the html into a proprietary format.

The last thing Adobe are likely to do is something that looks like open source. At the very least, it won't be free.

Using dropbox is different than working on something live. Like if I want to work on something right now, there is no way in hell I am waiting even 5 minutes for it upload. That's a total motivation and productivity killer right there. Total fail. Not to mention network connectivity issues, etc, etc.
