Well, don't forget there is 'cygpath' which is an executable which will
map for you. (You can use cygpath -w to get the windows path).

However, unless you are doing absolute paths, bzr accepts forward
slashed paths without any problem.

On my machine I just have a 'bzr.bat' which is:

@echo off
set BZR_PLUGIN_PATH=h:\dev\bzr\plugins
C:\Python24\python H:\dev\bzr\bzr.dev\bzr %*

the BZR_PLUGIN_PATH is just so that cygwin and win32 use the same plugin
paths. (And I prefer an exposed dir, since I modify plugins a lot).

Obviously your paths may vary, but this works well for me.

Also, you may want to realize that utf8 doesn't really work with
cmd.exe. It might work with rtv, or something like that. But windows
code pages are a little bit funky.
In my brief test, cygwin doesn't detect the codepage properly (win32
says cp437, cygwin says US-ASCII).

If you can get it to work, then certainly write it up.

But also be forewarned that you have to be very careful with
redistributing cygwin1.dll. It is a GPL not LGPL library. So if you
distribute it, you have to distribute all of its sources. And everything
that you have linked against it.
The general statement from the cygwin mailing list is "don't do that,
let people download it themselves".
Also, cygwin gets real unhappy if more than one cygwin dll exists on a
system. So there can be a lot of gotchas.

But if you can make it work, I'd be happy to hear it.
