Goals

• Learn how the core ME Community projects have
  been the catalyst for numerous ports, extensions,
  and expanded open source uses not previously
  envisioned when the community launched.

Why Open Source?

• Bring communities together and extend them
• Engage platform and application developers,
  ISV's, tools vendors, and operators
• Industry-wide collaboration on platform, tools,
  and applications
• Remove inefficiencies and barriers to innovation
• Drive common implementation and consistency
