Streams data out of Classic WoW addon-space into the outside world via a thin strip of pixels at the bottom right corner of the screen.
Currently it just subscribes to all events in the API and sends em over. Only tested on Linux.
WoW addons normally can't communicate with external programs, besides SavedVariables that are written to disk upon logout, and for good reason. But I was curious if I could implement a protocol to send data outside via pixel colours, without any nasty process hacking business.
I don't believe I'm doing botting scum any favours, since they inject their garbage into the process anyway, (or call ReadProcessMemory?). Since this is a one way channel, controlling the character with emulated input is a whole other bag of worms anyway.

Change the colour of your fancy RGB mouse/keyboard based on your mana/hp values, druid form, warrior stance, etc.
-
Display your guy's position on a world map on another screen.
Messages are sent with Cerealize_Send("Hello world!")
Not doing any fancy bitfield stuff. Messages that don't fit into the pixel strip get chunked up into several packets. \n indicates the end of a message (like serial I think).
Byte 1: Packet number
Byte 2: Checksum (Sum of all bytes except the first two, modulo 0xFF)
Rest of bytes: String encoded as UTF-8
