Bidirectional Communication over UDP

[lmnotran]

Hello all,

Our team is wondering what the best way is to communicate between an Arduino on the robot and the driver station. We have looked into using UDP but have noticed that on the FMS White Paper rev.A UDP communication on ports 1130 and 1140 is directional. It is my understanding that UDP by nature is direction-agnostic - our mentor made a comparison to standing on a mountain and shouting and whomever hears it, hears it. Is it possible to communicate back and forth on a single port using two UDP streams and filtering out data that isn't intended for that listener?
