Yes.  In fact we had some internal team working on win32 and macosX
versions of u-boot some 6-8 weeks ago, but like with many things we
never got any feedback.  I've asked the new software team leader to
investigate their status.

Yes.  I recommend to read the (short!) DFU specification before trying
software development related to it.  DFU has a 'Runtime' and a 'DFU'
mode with completely different USB descriptor set.  So everything looks
fine here.

The details are really easy to understand, and the official DFU
specification is linked from the OpenMoko wiki.
