in the wootedit repo[0] you can find a very simple (but working) collaborative notepad implementation, based on WOOT algorithm[1][2].

if you ever wanted to know how all those collaborative editors were done... look no further! ;-) wootedit is simple, but complete implementation of such editor, with UDP-based network communication. currently, it was tested under GNU/Linux only, but there are no platform-specific code (except some socket API), so porting it to another OS should be trivial.


you will need IV[3] and ARSD[4] libraries to build wootedit.
