  1. BizTalk Server 2006 R2 Evaluation Edition

  2. BizTalk Server 2006 R2 Branch Edition

  3. BizTalk Server 2006 R2 Developer Edition

  4. BizTalk Server 2006 R2 Standard Edition

  5. BizTalk Server 2006 R2 Enterprise Edition

Most are pretty self explanitory except for the Branch Edition (BE) –

– two or more BE’s can’t talk directly to each other,
must go through a Enterprise Edition
