gem install globalchat

https://rubygems.org/gems/globalchat

Should work on Mac, Windows and Linux. On Linux you need a lot of dependencies but it will work.

sudo aptitude install build-essential bison openssl libreadline5 
  libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim 
  libsqlite3-0 libsqlite3-dev sqlite3 libreadline5-dev libreadline6-dev 
  libxml2-dev git-core subversion autoconf xorg-dev libgl1-mesa-dev 
  libglu1-mesa-dev cmake libqt4-dev

If you're really crazy to try it

And I was able to achieve a degree of success in Windows with Ruby OCRA bundler, the EXE can be found here:
