since "Running unsigned applications like this will be blocked in a future release..." wouldn't it be good to have a version of Jmol that has no access to the users computer thereby trying to reinstate a sandbox as for the unsigned applet? May be just 'download-like' capabilities via a file dialog.

That's not what that message means. It just means it is an untrusted applet. The applets are now signed by a trusted chain of authority,  so you should not be  seeing this message. I'm not seeing it anymore on my machine; may be some settings still needed on yours. Anyway, it's not the applet doing that.
