- multiple local consoles (standard input/output, log files)
- socket consoles (Q3A compatible rcon (but this feature will be in Nexuiz 1.5.1), Telnet connection, UNIX socket - especially: reading the console of a running server)
- random map selection for Nexuiz, building maplists of wildcard expressions
- currently in progress: IRC spam (Nexuiz game results written to an IRC channel - of course only into your OWN channel)
- (the plugin example) outputting the current date when a player says "d"
- chat functions
- posting game results on a website
- perhaps running AS a special IRC server and having the console in a channel, in a window of your favorite IRC client (bitlbee does a similar thing for instant messaging services)

Have fun!
