I'm sure it is.  If you are a member of the AirDrop Yahoo! hroup, then
you'll have seen that some people are working on using SDIO.  The
AirDrop itself doesn't have an SD connector, so that hardware platform
is not likely to help you.

The WiFi adapters that are readily available are all SDIO as far as I
can tell.  There was some e-mails on the AirDrop group about
publicly-available information on SD/SDIO.  However, concensus was that
you'd probably need to stump up the cash to become a member of the SDIO
club.  I'm not sure how far that will get you because the SDIO interface
is one thing, the way to access the chipset/firmware is another which
may require vendor support.

The nice thing about the CF cards available is they all use one or other
of the two available chipsets, and a lot of work has been put into the
AirDrop PRISM drivers by quite a number of people, so that does work.
