Anything in your pack-rat's sack? :-) Contrib on ftp.x.org. Or try NCD (Network Computing Devices). The LBX (Low Bandwidth X) was developed by Mike(?) @ NCD and given to the X people for inclusion. They wanted to modify it somewhat before the released it. I believe the NCD code is out there under the name XRemote. It's moderately useful for point-to-point links where the remote X server is the only addressable device on the other end. NCD originally implemented it for serial rhater than ethernet connection of their X terminals to host systems where existing ethernet was too expensive or just not there. Later, they expanded its role to use it on modem links, once modems caught up with higher serial speeds. Or, you could look at the "hackers" archive. 8-).
