After looking through these forums, the twitter dev wiki & documentation, and elsewhere, it doesn't appear that there's a way to specify the media that gets displayed inline on #newtwitter.
For embedding video for Facebook share, you include this (& other) meta tag to specify the media that is displayed: <meta property="og:video" content="video url (.swf only)"/> Does a similar method exist for #newtwitter? I'm specifically interested in specifying a .swf URL.
