What to do?

• Time synchronization protocol without security
• Application use GenericComm for TPSN messages
• Application use SecureGenericComm for other
  messages
• Co-existence of GenericComm and
  SecureGenericComm
• Clear, but need more memory
• Time synchronization protocol with security
• new CC1000RadioIntM.nc
• new CC1000RadioC.nc
• new RadioCRCPacket.nc
• new GenericComm.nc
