dictionary integration for non-native speakers

[JostSchenck]

I would love to have the possibility of integrating some freely available dictionary -- like in eBook readers, where you just long press on a word and some bubble pops up, showing a translation, or explanation.
The reason I'd love to see this is: many years ago I learned English mainly by playing text adventures, starting with "The Hobbit" on the ZX Spectrum, later with Infocom games. Now my twelve years old daughter is learning English in school and is in desperate need of motivation. I showed her Wishbringer and she loves playing it using TextFiction on her mobile. However, changing apps for looking up unknown words is pretty cumbersome ... I think this would be a great feature for many people, and especially for language learners. FreeDict.org for example has free dictionaries in a documented XML format.
