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 to know nothing about LBX, they simply connect to the
lbxproxy as if were a regular 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.
Note that current X servers don't support the LBX extension, so this package is
only useful to connect to old X servers.
