I would disagree. On an ABR you can summarize area 0 addresses that
then are sent to the other area on the ABR.
Thomas - as to your last statement when redistributing connected you can
use a route-map and limit it to just the loopback so you don't have the
problem you mention.

The area range command is always inbound to area zero - i.e. your are
summarizing an area at the abr entering area zero. You cannot summarize
area
zero with it.
