I've added basic support for bitchat Geohash channels over at https://coolr.chat

Still some work to do, but you can easily chat with bitchat users. New messages from any Geohash will show up in separate channels as they come in and you can also just add the channel manually by doing

#bc_9q8yy

Once in a Geohash channel you can also simply type the command /geo to open up that Geohash location. I still need to work on mentions, and other things, but its working!
