An XML + JSON payload seems reasonable, but I wonder how long it would take
for native apps to interop with web apps. My original plan for adding custom
MIME type support to Chromium was to avoid security issues by confining the
custom types inside Chromium--they'd work when dragging/dropping or
copying/pasting within the browser, but wouldn't be visible to, say,
Photoshop. Ideally, there'd be cooperation about the browser vendors so it'd
even work across different browsers.
