The cache is part of GE, nothing I'm doing is changing the way google earth operates and they are free to kill the cache whenever they feel like it. The only thing I'm doing is making use of the features they provide.
Show me where it says what and where a "Network Link" can access or point to? Also the "Network Link" is made for automation of views and features.
While there is mention in section one of "(e.g., you may not use the Google Software in an automated manner)", the Network Links exist for this sole purpose and Google's software has total control over the rate at which it allows (if at all) these links to be used and accessed.
