libice6 6.8.2-10.3 (amd64 binary) in ubuntu hoary

 libICE provides an interface to ICE, the Inter-Client Exchange protocol.
 Motivated by issues arising from the need for X Window System clients to
 share data with each other, the ICE protocol provides a generic framework for
 building protocols on top of reliable, byte-stream transport connections. It
 provides basic mechanisms for setting up and shutting down connections, for
 performing authentication, for negotiating versions, and for reporting
 errors.
