Note that about 2/3 of the faster (>1 Gb/s) mirrors have rsync.

Having a setup that first downloads from a default mirror, and then uses rsync from other mirrors for any missing packages, would be efficient.

Note that downloading a single large package (such as Openoffice or Libreoffice) is not the same problem as downloading a multitude of relatively small packages, which would be typical of most Mageia downloads. Excepting ISO's, of course.

The geolocation of mirrorbrain could be useful for deciding the initial mirror. Just don't use the directory download if rsync is not available on this initial mirror.
