J.D. Wren,

The design sounds good.  A full kitchen sink design. :)

Just one little thing on this.  If you put a jumpers in to support
nibble mode, support not using the SPI signals for D0/SDA and SCL--you
might want to use those signals with a real SPI peripherial.  Or is
that solved with CS signals?  I'm not a big SPI user, I just read the
spec that was pointed out here the other day and this was on the top
of my head.

Now I really want to stuff an SD card slot on a board and start playing
with them.  Low pin count, removable, cost competative, etc.  Sounds
good to me.

Cheers,
David
