title: XUL runner as GUI framework for my application,what am i missing here?
body: <p>recently i was introduce to the mozilla XUL runner as framework for front line GUI 
  this seems to be idial framework to me ( none GUI person ) based on xul and js for events 
  and gives me the possibility to use c++ as back end ( xpcom  ) . its seams to good to be perfect . 
  my question is for the guys that have expireance in this frame work and can give me some points on the limitations of this frame work. 
  and also can i base commercial software on XULrunner binary ? some one knows about this license matter? </p>
