I can’t believe I never heard of this before now, but apparently there’s a Dark Age of Camelot server emulation project:
Unsurprisingly, the most popular server is based on classic pre-Trials-of-Atlantis DAoC.
Not that Bast3 needs more things to distract me from it, but I’ve been tinkering with it a bit, and may eventually put up a custom server. Not soon.
