lbxproxy 6.8.2-10.2 (i386 binary) in ubuntu hoary

 Applications that would like to take advantage of the Low Bandwidth extension
 to X (LBX) must make their connections to an lbxproxy. These applications
 need know nothing about LBX, they simply connect to the lbxproxy as if were a
 regular X server. The lbxproxy accepts client connections, multiplexes them
 over a single connection to the X server, and performs various optimizations
 on the X protocol to make it faster over low bandwidth and/or high latency
 connections.
