Great!

$ cat t2.rb
require 'hotcocoa'
include HotCocoa

application do
   on_notification :distributed => true do |note|
     puts note.description
   end
end

$ ./miniruby -I./lib t2.rb
NSConcreteNotification 0x185f9b0 {name = O3EngineChanged; object =  
brte*04271800; userInfo = {
     DisplayID = 69670912;
     EngineType = 1651668069;
}}
[...]
NSConcreteNotification 0x16cb8e0 {name = com.apple.iTunes.playerInfo;  
object = com.apple.iTunes.player; userInfo = {
     Album = Damnation;
     Artist = Opeth;
     Genre = "Death Metal";
     Location = "file://localhost/Volumes/Data/music/Opeth/Damnation/03%20Death%20whispered%20a%20lullaby.mp3 
";
     Name = "Death whispered a lullaby";
     "Player State" = Playing;
     "Store URL" = "itms://itunes.com/link?n=Death%20whispered%20a%20lullaby&an=Opeth&pn=Damnation 
";
     "Total Time" = 349805;
     "Track Count" = 8;
     "Track Number" = 3;
     Year = 2003;
}}

I also checked that posting a distributed notification works.

$ cat t3.rb
require 'hotcocoa'
include HotCocoa

application do
   notification :name => ARGV.first, :info => {'123' =>  
'456'}, :distributed => true
end

Note, I had to apply the following patch before.

    end

Great work!
