Here is one - Linux on Cygwin on Linux

[Steven Edwards]

Here is a good one for someone to test. 

The User Mode Linux people have done it. They are working on a port of 
User Mode Linux to Win32. This has been something I have been wanting to 
see for a while so we can use Linux as our Posix subystem in ReactOS by 
moving parts of UMLwin32 in to back to kernel mode. Right now you still 
need cygwin but if someone wants to try running it under Cygwin on WINE 
here is the url:

Thanks
Steven
