lsnd

lsnd is an ad-hoc server for Laser Squad Nemesis, which I hacked up as a stop-gap solution after the official server went down.

I have an instance running on my own machine - information on how to use it.

Source repository.

Setting up your own server may require a fair amount of experimentation and fiddling - I suggest you contact me directly if you want to do that, and I'll give some guidance.
