I was trying out JanusVM in my VMware server. It’s a linux based OS with this few key components, openVPN, Squid, privoxy and Tor, packaged neatly into a VMware “appliance”.
Basically it provides a layer of security and privacy for most TCP based applications, like IM, web browsing, etc, even DNS requests are passed through Tor. Most importantly, it provides you with access to sites that are filtered off by your ISP transparent proxies.
