What parts are you meaning there? The USB access? How would I solve the graph processing problem I have in a typically navigation app? Loading the full graph from USB into RAM? Or traversing the graph on a slow USB stick? I'm still not convinced. I can see the potential for games via WebGL + storage. But especially navigation software looks not really possible.
