Hi Keith,

i just updated the documentation, which can be found in the folder 
"doc". It contains some C++ code which describes the data package which 
is sent via network. There will be no major changes to the 
GameController until the RoboCup in Graz is over.

The demo client was only intended for testing purposes. The heartbeat 
broadcasted is not necessary and may be used to have a visual feedback 
about active robots in the GameController gui of future versions. If 
this feature is available, i will add a specification of the hearbeat 

If you have any further questions or feedback please feel free to send 
me an email.

Best regards,
