"RetroShare is a Open Source cross-platform, Friend-2-Friend and secure decentralised communication platform. It lets you securely chat and share files with your friends, family and coworkers, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication. RetroShare provides filesharing, chat, messages, forums and channels"
Doesn't that sound like a nice alternative platform for Kritterbox?
For example, with the Feed Reader plugin you could have it automagically import new threads into a separate anonymous forum inside RetroShare.
And it is already possible to run RetroShare on a VPS, over a VPN or even over Tor but your friends (the connexions you make in RetroShare) will still know your IP. However with the next release an option to establish the connections over a tor hidden service is also in the making which will allow users an extra layer of anonymity over the security already offered.
RetroShare also replaces IRC with totally anonymous chat-lobbies, TorChat for encrypted chats and Skype for encrypted VOIP conversations.
I could go on, but it's best you check this out for yerselves if you haven't already:

Official download page:
(I'd personally recommend using the portable version since it locates everything into a single folder, which for example is easily moved onto a (encrypted) usb -stick and carried along in my pocket)
In hope of seeing more kritter activity in the RS-universe,
