That means unix sockets must work correctly. If they do you can use the
-nolisten tcp and :0.0 display

AUTHFILE=`mktemp /tmp/auth.XXXXXX`
COOKIE=`dd if=/dev/random count=1 | md5sum | cut -f1 -d\ `
xauth -f $AUTHFILE add :0.0 MIT-MAGIC-COOKIE-1 $COOKIE
XWin -auth $AUTHFILE
rm $AUTHFILE

maybe 
XWin -cookie `dd if=/dev/random count=1 | md5sum | cut -f1 -d\ `

will work too.

Both methods are not tested but may help as a starting point. I even
don't know if /dev/random exists in cygwin. If not, /dev/windows should
be fine too.
