Good idea, but if all you want to do is cache the data in your area, you can do this by creating a tour in GE.
If you have GE Plus, you can draw paths anywhere and fly along the paths. If you have GE free you can put a collection of placemarks into a folder and fly the tour from placemark to placemark. Put a bunch of placemarks into a folder and fly the whole folder. The order is top to bottom, as you ordered the placemarks in the folder.
It takes a lot of experimentation to get the results you would expect. At first you will experience "bunny-hopping" from placemak to placemark. This can be fixed by going to Tools -- Options -- Control -- Advanced. Set the Driving Directions Tour Options for a shallower camera tilt angle and longer range, and change the speed. Then set up a new tour and see if it's how you like it. It all takes a while to get the hang of.
Is this kind of what your after? It does get the data in your cache. You may also want to set your cache size to the maximum of 2GB. I've found that 2GB covers a pretty good sized area, but it does depend on the quality of the images in your area.
