Why would we need geo distributed build hosts?

If we wanted geodistributed output (ie, where the builds are actually
hosted), that would be one thing .. and maybe even needed if there is
enough bandwidth for downloads.

But geodistributed bulders, to me, are self defeating.  If you need MORE
builders, put them where the repos they build against live and use them

What would be the benefit of geodistributed build machines?
