Okay it's an interesting question. 100MB for LW, 100MB for Firefox ... some other things, maybe graphics work with MGI Photosuite , can be a problem. Not with newer computers I guess.
As for hash (The IDs of my files), I assumed that was stored at LW head quarters. If someone does a search, you tell me LW has to reach out at that moment to millions of user locations to read their hash? I thot when we connect, or add files, or refresh, it gets sent to head server. That's the way to handle searches. Or is it at both places.
By the way, does anyone else use Photosuite, and have it suddenly crash and disappear? Is that a Microsoft program?
