SONY will effectively remove support for BatMUD's Batclient due to disallowing "Other OS" (or Operating System) from being installed/run on the Playstation 3 gaming console.

For more information, please see: http://blog.us.playstation.com/2010/03/28/...e-v3-21-update/

Sadly, Batclient will stop working for all PS3 users after the FW upgrade as your Linux installation will no longer be available.
