You might consider using one of the alternatives mentioned below as more people have analyzed their security and reliability from a privacy/anonymity point of view.
Also, for cloudish to work, one would need quiet a lot of nodes spread out over the whole world.


Tor - an Onion router application. It works like cloudish whereas cloudish did only http and Tor does all TCP protocols (except SMTP and maybe a few others). One can even run a VPN through Tor. So with Tor you can secure all traffic: browsing, MSN (altough beware that you have to more or less identify yourself when creating an MSN account), ftp, etc.
I2P - from their website: "I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other.".
FreeNet - a network in which one can share information, completely anonymous. From their website: "Freenet is free software designed to ensure true freedom of communication over the Internet. It allows anybody to publish and read information with complete anonymity.". Using FreeNet is quiet a challenge as it has no searchengine, so you need to know the exact name of a document to retrieve it.
GNUNet - like FreeNet
Entropy RSA - also like FreeNet
Mixmaster - mixmaster is a method for anonymously sending e-mail
Mute - anonymous filesharing; no direct connections but also no encryption
Freehaven - The Free Haven Project aims to deploy a system for distributed, anonymous, persistent data storage which is robust against attempts by powerful adversaries to find and destroy any stored data. This model of decentralized system has been classified as peer-to-peer by recent popular media.
Grapevine - "We are creating an anonymizing storage network - a network that resembles the World Wide Web, but is capable of allowing people to publish and retrieve information without fear of censorship or surveillance."
Pastry - Pastry is a generic, scalable and efficient substrate for peer-to-peer applications. Pastry nodes form a decentralized, self-organizing and fault-tolerant overlay network within the Internet. Pastry provides efficient request routing, deterministic object location, and load balancing in an application-independent manner. Furthermore, Pastry provides mechanisms that support and facilitate application-specific object replication, caching, and fault recovery.
The Circle - The Circle is an open source scalable decentralized peer to peer application. What does that mean? Well, there's no central authority running the show. No entry taxes either, no censorship, and (in theory) no weak point which can break the whole system. No one even owns the source code. As long as there is one Circle peer running, anywhere in the world, there's still a network.
IIP - The Invisible IRC Project (IIP) was originally created so that people interested in facilitating privacy and free speech could work to these ends in an equally secure and anonymous environment. It has now become a haven for anyone seeking anonymous, encrypted Internet Relay Chat.
