I came across this application and wanted to share it with all other WM users.
Its a simple application which would send your location to an central server which in turn would give you nearby parking lots through your web browser. It uses virtual gps port so it wont interfere with GPS navigation. I just installed it any haven't got a chance to really test it out as i am inside a building.
Give it try!!
