The disk footprint is not very much larger, but I assume that the
amount of bandwidth needed for a first checkout can easily be 10x or
50x.
(then, if you keep the checkout around, pulling new revisions is very
efficient)

That said, it seems there are tools to optimize the internal structures
of an hg repository so that it takes less disk space (and therefore
less checkout bandwidth). I don't know whether Dirkjan intends to use
that.
