Marty, thanks for the interesting insight.

Jim Gettys (at http://www.gettysfamily.org/wordpress/?p=27 ) mentions
how Marvell helped free up the Marvel wifi driver.  He also talks
about how the Marvell chip is crucial to the OLPC low power goals.
(Although the 300mw estimate for the running chip strikes me as kind
of high for use on a cell phone where one has maybe 3 watt-hours of
battery all together.)

I wonder how its power compares.  I'd certainly expect TI to have more
engineering and manufacturing talent on hand for building a really low
power wifi chip.
