Instead of FORTRAN, someone should try writing a Minecraft server in something like ALGOL or FORTH.

Algol 68 actually isn't too bad of a language to work with, and there's a modern interpreter easily available. Unfortunately it lacks all support for reading and manipulating binary data so I think a Minecraft server would be nearly impossible.
