Nature Valley (the granola bar company) is apparently sponsoring an effort to make a street-view style tour of trails of National Parks available. They just started with Yellowstone, Great Smoky Mountains and Grand Canyon NP's but I would assume if they continue with this effort that Yosemite would not be far behind. Haven't really made my mind up if this is cool or not, but sure is a neat idea.
