Answer 1

I had a google map project that I needed offline. I found Bing Maps (https://www.bingmapsportal.com/ISDK/AjaxV7) is much better offline and switched my project over to that and I'm happy. I ran the google and bing version side-by-side in offline mode and Bing was great. Whereas google would immediatey fail on tile loads, Bing maps cached more tiles and appeared to even resize zoomed tiles to at least give you something in offline mode.

I know the question here is about Google maps; but if you don't care about bing vs. google and really just need offline support, I'd highly recommend trying Bing maps. It solved it for me.
