Is it possible to programmatically install wordpress theme plugins

My dream is to include a php file in a theme that checks if a set of plugins is installed and installs those that are not. It seems like a set of dependencies for a theme, but also just a good way to batch develop a theme to include a set of good plugins.

My questions...

  • Is there something similar?
  • Is it possible to get one php file in the theme folder?
  • Are there obvious holes or problems with this approach?
  • How can i do this?
    • Can I list installed plugins from the themes folder?
    • Can I upload and place plugin files in the plugins folder?
    • Can I activate plugins from the themes catalog?
