About threading. I haven't fully explore this yet since I haven't gotten to my relevant projects yet. I did read some material that suggest polling in an idle handler to push things back to the UI thread.

I was planning on experimenting with gobject . In theory Qt switched to the gobject main loop which means I should be able to use gobject callbacks. I use the idle and timeout callbacks to push tasks between threads in my PyGTK apps and is all the synchronization I need.

(It saddens me that Qt doesn't have thread safe signals/slots like gobject/GTK do)
