The one thing I would note about many of the "roll your own" systems is
that typically they consist of a certified module (mPCI card) and a
single board computer.  As long as you stick to single radio setups,
then typically the only thing required is a Declaration of Conformity
(unintentional radiator testing).  This is quite a bit cheaper than a
full certification that has both the intentional and unintentional
radiator tests.  That said, it *does* require the certified module to
have been certified with a wide range of antennas, which is not commonly
done today.

Oh, and consider our horn tooted.  :-)

One reason the non certified manufacturers are not certifying their 
equipment is because of the changes that take place in such short time 

To certify a system, the radio card, the antenna AND "the board" which 
drives the card has to be certified together as a complete system.

The roll your own non certified equipment changes very fast. It's always

a newer faster board or a newer better card. Just a few months ago the 
CM9 was the rage of Atheros, now seems like the WLMG54 is popular. 
couple months ago wraps were the ticket and now it's war boards..

I don't think it's likely to see too many certifying systems under these

conditions. But I'm sure they could easily be certified. it just takes
