Hi,
I wrote some code to fulfill the proposal you discussed two years ago, using
xclip and perl to yank image file in link format for org, and save the file
named after the image's timestamp.
Which means it's working for xwin clones, and I'm currently using Ubuntu 12.10.
The function is named
*bump*
I think this would be an awesome feature. Some of us use highly-graphic OSes
such as OSX and Windows (or maybe Linux with Gnome), and being able to
interact with the desktop is a great feature. Imagine being able to drag and
drop a file directly to emacs and delegate the attachment to org,
