No, Amazon Cloud Drive and Microsoft SkyDrive do not have shell integration. You need to upload using a browser.

Hopefully, Google Drive will be similar to Dropbox wherein, you will have a G-Drive directory in your hard disk. Microsoft has a similar product too - it is called Live Mesh.

There IS Skydrive shell integration:

-you can easily mount a Skydrive folder and Office will recognize the file originated from Skydrive and show relevant information (e.g. other editing the file)

-Office 2010 has a 'Save to Web' function

I am curious how to mount Skydrive. All the approaches I have seen rely on unofficial tools which seem to have stopped working about 6 months back.

It would be great if you know of something that still works.

And on a Mac? Linux?

I'm unsure how this comment is helpful. The conversation goes like this:

  Person 1: Microsoft SkyDrive doesn't have shell
            support. It's browser-only.
  Person 2: Sure it has shell support, but it's
            Windows-only.
  Person 3: But it's not *CROSS-PLATFORM* shell
            support!

There is a Mac version and technically you can use their official API for Linux as well.
