Advanced Caching

I'm wondering what people would think of an advanced caching ability for people with high speed lines and lots of hard drive space. Right now it seems at max level I cache more or less the sim I'm in. Which is nice, except as soon as I Start to move towards another sim, especially flying, I take a hit..
What if you cached the the one you were in, as well as the 8 surrounding it. As you moved it would cache the next 3 in the direction you travelled.

I'm just thinking something like this might make certain kinds of travel a little nice so you're not flying around, then suddenly have a building pop up around you.

Turn your draw distance to 512m

draw distance is different than what I suggested. That would have it actually draw that far, not just cache that information. It would be easy for someone to have a fast connection, big hard drive, and not have a video card capable of drawing that much.

Then I believe the Feature Suggestions forum would be appropriate for this post since what you are asking for doesn't exist, I too would like to see this feature:

cache download in SL is limited, wont help if you have anything over 2mbit, except for video / audio (well ok audio isnt demanding ~.~)
