I just want to point out that communications over an SSL connection are secure from snooping between your browser and the receiving server, with the exception that routers in between can see the destination (not the contents) of the communications.
If you are on a network that is being monitored, you can therefore provide communication privacy by connecting to a proxy server outside the network via an SSL connection. The monitors will be able to see that you are connecting to the proxy server, but will be unable to know what your actual destination or communication content is.
Hope that helps!
