Real Time Streaming

Has anyone ever used the Arduino to stream data in real time? I am interested in setting up an accelerometer and maybe gps to so make a wireless data system. I want to use the XBee to to connect remotely. I was also thinking of using LabView to process/display the data.

Yes. For example the Arduinoscope example streams all six analog inputs to a Processing program which then produces a crude oscilloscope display.
