Where does the integrated Sametime client store the location information?

I am using Lotus Notes 8, the full featured Eclipse based version, with Sametime and really like the location awareness.
Unfortunately I messed up some location information by mistyping or saving incomplete data by accidentially hitting the enter key. I was wondering where that location information is stored and what format that data is. I found that the information is stored in a XML file containing the information I typed in, the IP I had at that location plus a MAC address (of the default gateway I guess).
The file is located at {your Notes data directory}\workspace\.metadata\.plugins\com.ibm.collaboration.realtime.location
