If you are looking down on the globe from on top and your text is rotating around the globe's equator then this is possible. Track Motion uses 2-dimensional material. If you want to see a full 3D object then you'll have to create your logo in 3D software, export it as a movie file, then use this in Vegas Studio.
Is this the sort of thing you're talking about? http://www.chienworks.com/msbc/wgod_5_6-256k.wmv (about 5.2MB). I created the logo in Micrografx Simply 3D as a .avi file, then used it as a video clip in the Vegas project.
