• Bring your laptop*

Aftermath

• Moved forward on sockets with a basic client - server example made and presented by acynonix
• Decided to use IP/UDP stack for control signals
• Made network latency tests that gave an average of 16ms over 3 hops in our lan
• Decided to abolish the, now redundant, identifying 2 bits used for serial communication

Seems like we'll be going forward with C/C++ after all. Oh well :) ~ skmp
