For what concerns Google's policy concerning NAT calls being treated as spyware activity. I am now proxying Google for the JSON call, so it will see the IP adress of our web server in stead of the Network Adress Translator. It helps for the moment. Now I wonder if our own calls will make Google complain as well, we will see.
One thing I noticed, when encountering the "we're sorry ... you have spyware" message from google is the following link in this message: http://www.google.com/support/bin/answer.py?answer=86640 very interesting !! I guess lots of you are using meta search enigine to search Google. This message explicitly states this is against Google's terms of service (http://www.google.com/terms_of_service.html) Peter
