Great questions. I currently filling the documentation so you could watch the repo or star it and keep an eye on it. The idea is that components will be like objects and elements so you could easily access them. Take a look at this example:

<div> { this.each(profiles);

  <!-- Render all profiles -->
  <Profile>

} <div> { this.find('Profile').setIsMyProfile(true);

  <!-- render personal profile -->
  My profile.
  <Profile>
}
