I'm with Chad here... Dynamic Data structures sound cool and even a little sexy, but they are by definition contradictory. Your data structure is like the foundation of your application: you want it to be as solid as possible. Allowing for extensibility for future improvements is one thing. A data structure that changes at run-time would be a complete mess.
But then, perhaps we're misunderstanding your question. Feel free to elaborate if you feel misunderstood.
