Glad to know it is of some use. :-)
The dev kit is just an experiment to help end users of the library.
And please take note libftdi-1.0 is not formally released. I think
the main project using libftdi-1.0's async I/O feature is urjtag.
Maybe I should make one for libftdi-0.19 for Windows as well
(one stop binaries for libftdi-0.19 and libusb-win32 22.214.171.124,
documentation to use the device driver mode or the filter
driver mode, etc).

It is not mine. :-) Jie Zhang is the original author and Uwe Bonnes is
the main contributor to libftdi-1.0 now.
The main difference is the dependency on libusb-1.0. And under
Windows, that means using WinUSB driver right now.
There is a version of libusb-1.0 Windows which will work with
libusb0.sys but it is not matured yet and not integrated into the
main libusb-1.0 git tree yet.

For Linux and Mac OS X, probably yes now. For Windows, there is
this complication of the slow release of libusb-1.0.9. Hopefully
it will be released really soon. Still it is good that you start to
experiment with libusb-1.0 and there are quite some projects
moving from libusb-0.1 to libusb-1.0 already.

I can make a devkit for MinGW-w64 64bit as well. :-)
