How tough is that to write a driver for? And for what platform
are you doing it? (if you don't mind my asking)

I use the D2XX drivers with GPIO, but I usually end up using libusb
and libftdi instead. Same functionality, a bit less buggy.

There's metal on the sides, but it's not contiguous with the metal on
the bottoms. I've checked under a microscope, and the PDF spec
agrees.

Dave,
Results are very much dependent upon distance and obstructions. 2 to 5
meters
seem to be the sweet spot. I tried modules with the antenna build into
the board
without much success. Switched to a 10cm 2.2 dBi and am now considering
switching
to a larger 5 dBi antenna.

Yuck! I'll stick with the FT232BM. (LQFP-32, easy!)
