  activities :generate_flv, :upload_flv
  ...
end

class ScreenshotActivies
  extend Activities

  activities :get_movie_duration, :grab_screenshot, :upload_screenshot
  ...
end

workflow do
  video = download_video_activity

  flv_activities = FLVActivities.new video
  scr_activities = ScreenshotActivities.new video

  flv = client.send_async(:generate_flv)
  scr = client.send_async(:activity2)
  
  wait_for_all(flv, scr)

  cleanup
end

fe de erratas, donde dice:

client.send_async :generate_flv, debe decir (client o some object).send_async :flv_activities
client.send_async :activity2, debe decir (client o some object).send_async :scr_activities

tambien puede q send_async reciba el nombre de la activity en lugar de una instancia de la misma
