I'd be very interested if there's anything you can say as to *why*
Mozilla is doing this.  Why not just continue with the Mozilla
home-baked mechanism, thus remaining immune to any unexpected changes
Microsoft may make to BITS in a future Windows ?

The Mozilla mechanism does seem to work fairly well, with the possible
exception of the strange phenomenon of some PCs being randomly,
inexplicably and unpredictably much slower to receive a scheduled
update than others - is the move to BITS anything to do with improving
/that/ situation?
