Source code: https://github.com/jsilverMDX/GlobalChat2 Bonus: RubyMotion version Definitely planned and in the works: Android Ruboto version Not yet planned or in the works: Windows, Linux Reporting in on IronRuby, it feels like a huge dead end. Takes ages to get anywhere and there's no toolchain support in OS X, though it builds under Mono. It's incredibly frusterating because it seems that the language they built is actually 99% of what it needs to be to be a great Ruby next to MacRuby. But there doesn't seem to be an interest (?) even by Xamarin, Mono developer, so I've given up on it. Shoes may be used to make the Windows or Linux versions. If anyone knows any other cross platform Ruby solutions, please let me know! Thanks and MINASWAN ! Jonathan Silverman
