Well - 

first you'd need to fix portage for Cygwin usage. Small stuff:
- user/group check is not reliable in windows
	* either remove or add "root" and "portage" users
- there's some userland check that fails, need to append WINNT5.0 if I
recall correctly
- there were some path issues, I think those are fixed - hardcoded paths
need to be fixed

So portage mostly runs.
emerge sync doesn't work as we have a few ebuilds with ":" in the name
--> cygwin interprets that as a drive letter 
--> write a sane rsync_exclude (or better, start a cygwin-only ebuild
repo)

Now you try bootstrapping.
--> the linker used to be really dumb and wasn't capable of repeated
compiles.
	* if that still exists the linker needs to be fixed - this will be
tricky
--> glibc doesn't exist on Cygwin, the cygwin libc is evil
	* either write an ebuild for cygwin-libc providing virtual/libc or port
glibc
	* I never managed to build cygwin-libc from scratch, it's evil :-)
	* porting glibc will be _a lot_ of work, cygwin libc is incomplete
--> many packages need lots of patching
	* extract patches from cygwin repositories, apply to ebuilds and test
	* never managed to get gcc to build, that'll be lots of testing until
it works reliably
--> now you should have a smallish system that can "emerge -e system" 

--> create an install image like the cygwin installer that plops in a
stage3 equivalent

--> start porting as many ebuilds as you can

People with some spare time and lots of motivation can try "Services for
Unix" instead of Cygwin
as far as I can tell it's not as buggy, but has been crippled so that
it's not easy to use.

Cygwin and SFU can co-exist and should share 99% of code, so trying both
is acceptable

I don't have the time for actual coding/testing now, but I'm willing to
provide ressources (rsync repo, cvs / svn repo, coordination)

If there are any questions left feel free to ask!

wkr,
Patrick
