Quadruple boot help

Hi everyone!

I have Windows XP, Windows Vista, Windows Server 2008, and Arch Linux all on one hard drive. I'm planning on adding more operating systems for study but these are the ones I have at the moment. I'd like to have them all come up on the same screen, unfortunately, arch linux is on a logical partition. I suspect this would cause some problems with the windows bootloader. For this reason, I'd like to have each windows accessible from the grub bootloader and cut out the BCD chooser thingy completely. While searching on google, this caught my eye: http://neosmart.net/forums/showthread.php?t=924

However, I don't know if it will work with three windows operating systems. What about these directions must I change in order to have every windows boot be its own option in grub?
