Having the client perform the task of indexing is great, but it also means I can index pages that only I am supposed to see. Which raises the question: are you going to do anything with the index and cached pages I've built up? If I index an interior facebook page, for example, will you ever expose the cached content to other users of historious?
What we might do is show lists of the ten most popular URLs, for example. Since those are indexed by many people, nobody will be able to personally identify anyone. We wouldn't even keep the page, but it's necessary for reindexing things if something goes wrong (e.g. we are thinking of changing the search engine, and it would require a wipe of everyone's history if we didn't keep the pages).
In short, no, we will never show your cached pages or even your URLs, except in very anonymized circumstances.
