Completely agree with you on that point.  I'd love to see Equinix, AMSIX, LINX,
DECIX, and the rest of the large exchange points put out statements indicating
their ability to transparently support jumbo frames through their
fabrics, or at
least indicate a roadmap and a timeline to when they think they'll be able to
support jumbo frames throughout the switch fabrics.
