How is that easier?  You have to test each experimental edit, and that 
requires a Linux kernel running SELinux.  Cygwin is not a Linux kernel.

Personally, if I were still experimenting, I'd spin up a VM configured 
like the system I intended to modify, do my work on it, then ship a 
completed policy set to the remote system.  Linux VM how-tos are 
off-topic here, though.

What point are you making here, exactly?  Do you want Cygwin to emulate 
one of them, or all of them, or none of them?

I think all three choices are doomed, each for a different reason.

That's why the Android SDK includes an emulator, which is a VM, just as 
I described above.

Are you aware that some of the text editors ported to Cygwin can edit a 
file over SSH?  For instance, vim:

    vim scp://user AT remotehost:password/path/to/file

The edit proceeds at local speeds.  A save takes a remote file upload, 
but you had to do that anyway.

You aren't going to find SystemTap or iptables tools for Cygwin, either? 
  Why?  Same reason: you need a running Linux kernel to make any use of 
them, and Cygwin is not a Linux kernel.
