This page should list all tools to embed content from a link. When a recognized URL is added, maybe Tiki could offer to convert to a plugin for nicer viewing?

Todo: evaluate all the options like was done for Slideshow framework stats comparison and integrate one to Tiki. Ideally, the same as for our XMPP solutions (Pàdé and Converse)
