loopmounting during kickstart

Hi, I am trying to create something for Fedora like Wubi does for
Ubuntu -- allow users to install Fedora from inside windows by
loopmounting a file on a windows partition as a drive while using
Fedora.
Can anyone tell me if this snippet can be used to make anaconda
install Fedora to a file on a windows partition?

%pre
#!/bin/bash
#----------------------------------------------------------------------------------------
# Mount windows drive
mkdir -p /tmp/windows
mount /dev/sda2 /tmp/windows

loop_root=`losetup -f`
losetup $loop_root /tmp/windows/virtual.disk.root

loop_swap=`losetup -f`
losetup $loop_swap /tmp/windows/virtual.disk.swap

loop_boot=`losetup -f`
losetup $loop_boot /tmp/windows/virtual.disk.boot

echo "part /boot --fstype ext4 --size 512 --ondisk $loop_boot" >>
/tmp/part-include
echo "part / --fstype ext4 --size 10000 --grow --ondisk $loop_root" >>
/tmp/part-include
echo "part swap --recommended --ondisk $loop_swap" >> /tmp/part-include
#----------------------------------------------------------------------------------------
%end

%post
#!/bin/bash
#----------------------------------------------------------------------------------------
losetup -d $loop_root
losetup -d $loop_swap
losetup -d $loop_boot

umount /dev/sda2
rm -Rf /tmp
#----------------------------------------------------------------------------------------
%end

#blah blah blah

%include /tmp/part-include

#blah blah blah


Please let me know if this will work, or any changes that need to be
done. In addition, it would be really nice if you suggest me a way of
testing if this works, and point me to some directions on creating
ISOs with my own kickstart files.
