Ubuntu's own summer of code

Define an event similar to Google Summer of Code, organized by and for Ubuntu.
Basically, the event would be like the Google Summer of Code, except that:
  * The event shall be open to everyone, not only students.
  * No cash reward. The motivation factor would be the fact that the contribution would be included in Ubuntu's next version (provided it is completed)
  * The event shall not be limited to code contribution. Packaging, documentation, I18n tasks shall also be submitted.
  * The event shall be synchronized with Ubuntu development cycle, thus every 6 months.
