Absolutely, AddThis can be used to share Flash content, like video players and widgets, "embedded" in pages. Your visitors are always ultimately sharing a URL, which ensures that your content can go as many places as possible. For sites that support Flash widgets, however, AddThis will ALSO pass along the embedded content, letting your user share the widget. iGoogle and Facebook are examples of sites that support this, and Facebook's treatment of videos in news feeds is a good example. For more explanation, refer to Embedded Content sharing.
