Yesterday I found the Wavr by Lucas Caro, a plugin which allows the user to add waves as embedded to the waves.
You just insert the code
and then you have the wave embedded in your post. Like showed bellow. The plugin requires the user to have a Wavesandbox account to see the waves, but then they can interact with the page directly. If not they just get an unauthorized page.

The plugin still have some more development, but it shows how easy it is to reuse conversation on ie blogs or Wikis.
