Hi,
Have you looked at the image side work done in Sophie?
You mean ExtendedClipboardInterface? Might be a starting point, yes. The double-dispatching is a bit questionable but that would be simple to fix.
For the VM-side, Sophie uses an odd mixture of ClipboardExtendedPlugin and FFI code - and how does that plugin relate to ClipboardPlugin? I'd think we want just one plugin.
Where can I get a source code of ClipboardExtendedPlugin or ClipboardPlugin (Is ClipboardExtendedPlugin just for Macintosh specific plugin?) I would like to choose a common interface for X11 clipboard.
Cheers, - Takashi
