Session ID for Buddy Tracking / Stop, Pause/Resume Buttons

My Idea,

if I start Buddy Tracking on my phone a unique Session ID will be created. I can send this Session ID to my Server to allocate the actual tracking. This will allow different tracks on the same day.

If I stop buddy tracking on my phone and restart it, a new UID will be created and send to the Server.

e.g. "8BA21D90-3F90-407F-BAAE-800B04B1EFAA".

This also requires a pause/resume button beside the stop button in Locus Buddy Tracking. Pause will stop sending the data and keep the actual UID. Stop button will stop sending and dismiss the UID.
