Remember that the "flat" option is only available at the mighty ArcINFO license level. – SaultDon Jul 12 '12 at 16:24

if i have understood what you meant by flat buffer on polygon, you could apply these steps :

  • feature to polyline.
  • Split at vertices
  • buffer with flat enabled
  • Append the original polygon to the buffer_result
  • dissolve on a commun value, if there's not a commun value, add a field to make commun value
