Keyword lookup

We could use a solution for keyword lookup that supports selecting any word and finding more about it -- definitions, reference articles, other matches in material flagged as reference material on the laptop. The flagged material could be in the XO core or in downloaded bundles.

This would presumably integrate somehow with

• the Journal / Datastore search (note: user:tomeu and Fabien C of Linterweb and ivan are discussing this as of Jan 2008)
• internal indexes that come with a bundle that desires to be searched
• the text-to-speech service being added to Sugar to support selecting a word and turning it into audio
• data bundles (similar to a bundle of MIDI files) of words, such as a system-core dictionary
