* might we want per connection values?

* :except => {:no_release => true}

  It is common to configure tasks to 'announce' deployments in IRC, Campfire,
  etc.  If you have 6 app servers, you don't want to see 6 announcements.  In
  Capistrano, this is handled via the :no_release => true flag.  Various tasks
  only execute on the 'release' servers.

  An easier way to meet this would be to introduce a :release role in the
  default setup

    role :release, "app1.example.com"
    
    remote_task :announce_in_irc, :roles => :release ...

  Drawback: Yet another thing to change when you migrate a project from cap to
  vlad

* 'dynamic deployments'

    role :app, "app1.example.com"
    role :app, "app2.example.com"

  Let's say that app1 and app2 need slightly different monit configurations.

  In Capistrano, you might approach this by making two additional roles, and 
  splitting your 'push a monit config' task into two. This sucks.

  Vlad makes the 'execution context' of a task available. In Vlad, you would:

    remote_task :update_monit, :roles => :app
      rsync "templates/#{target_host}.monitrc", "/etc/monitrc"
    end

* fine-grained tasks

    remote_task :update
    remote_task :symlink
    remote_task :migrate
    remote_task :deploy => [:update, :symlink, :migrate, :restart]

  Let's assume that this is a multi-server config with shared deploy path.
  The user wants to do only a single checkout. If we make "update" be one big
  task body that includes the update, symlink, and migrate steps,
  it is difficult for the user to override the roles for the particular steps
  they need to change.

  If we break these into separate tasks, they can say:

    Rake::Task["migrate"].options[:roles] = :master_db

  and the migrations will only run on the master db

* sudo / via how? and if we call it via I will stab ppl. "user" is sufficient.

* handling 'use_sudo'

  1. Check for this inside the 'run' command, and preface the command
     with 'sudo' if necessary

  2. Default this to 'false' in the reset method, and check for it
     in the default tasks that we provide:
       if use_sudo then
         sudo "blah"
       else
         run "blah"
       end

  Option 2 has fewer moving parts, but clutters up the tasks that care about
  this.

* Dependencies

  Task dependencies aren't settable when creating a Rake::RemoteTask.

* Apache configuration

  Pull in railsmachine/rails/recipes/apache.rb's apache configuration.  Needs
  erb to work.

* I really like tasks with naming <cmd>_<role> (eg setup_app,
  start_web). We could easily make the front end remote_task command
  look for such a convention and apply the :role => x automatically.

* from bousquet: get a couple of server environment recipes that prepare your
  machine that would be the golden ticket:

    rake vlad:prepare TYPE=accelerator | ubuntu | osx | osxserver | site5 | ...

  and have people maintaining those setups who depend on them
