Just a quick entry as I am busy studying for a two day exam that is this weekend.
Earlier in June, Google posted a response to an open letter on one of their blogs that indicated they are looking into the feasibility having Gmail encryption always on. Other Google applications such as Google Docs can use TLS/SSL, but it is currently not required unless the user specifies it.

Last year Rogers attempted to insert pages and frames into their subscribers browsers when they were surfing, and Google was not impressed.  According to Michael Geist, it is back.

Anyone want to make any guesses as to how long before Google and other web services just turn on HTTPS to stop this and deal with the increased performance requirements?
