Good point about waiting until you are able to build your package. :-). Mind posting your build_myapp.py please? I assume your previous post details all of your import statements, so I won't need that. BTW, to keep posts, short, you can use http://pastie.org or similar services. Looks like you figured this out already :-)

Qt can handle multiple threads:

• Multithreading and Concurrency Examples
• QThread documentation( probably easier to understand than the above examples

As for gps, you are probably fine using gobject until qtmobility becomes stable.
