I agree, I would like to see C# Mono included as well. People might also want to see C# .NET, but I don't think that is applicable here because we are talking about 64-bit Linux (the dominate internet platform) here.
ok cool, was just a little vague, you should've mentioned 'Windows' as C# (even F# http://www.servicestack.net/mythz_blog/?p=785) is cross-platform and runs on OSX/Linux with Mono.
