One nice use for rsync is off-site disaster
backups which one might run on a "trickle" basis.
For a variety of users, having something built into
rsync that works "on the average" is good enough and
avoids the complexity of installing a separate rate
limiter.

It sounds like Wayne's patch would be an improvement
to the rsync bwlimit feature.
