Bootcamp is just a partition and "Windows driver disk" maker application for MAC OSX. It has been around since before OSX Tiger, but was released for beta testing on the Tiger disk.
It has since expired, and Leopard is required to use BootCamp "legally", however if you have .dmg laying around somewhere it will work.
As far as FFXI on a MAC, you are limited to really these two options:
1) Run Parallels or VMWare Fusion within the MAC OS, and enable Direct3D emulation. This is indeed a slow solution but will allow functional ffxi if you turn down the graphic configurations. Its not pretty, but if you really want to you can make it work.
2) Run Windows natively on the Mac. Because of the Intel based chipset and other hardware, windows works natively on the system. You do have to have some custom Mac drivers that bootcamp provides in a fancy lil installer, or you can build / find your own across the internet. Bootcamp does not emulate the windows envrionment or eat up any additional resources other than if you use the base installation there is a systray icon that allows you to set your boot partitions as active.
One more thing to take into consideration here is the boot manager of HFS filesystems is EFI and not the standard bootldr of our old DOS knowledge. If you indeed decide to dual, tri, or even quad boot your Intel MacBook Pro I recommend a program like rEFIt (just google it) that is a boot manager for both EFI and old school boot configurations.
Personally, having MAC OSX, Windows XP, Vista and Ubuntu make the Mac hardware just plain sexy, and all versions of Windows apparently run more smoothly than on similar "Microsoft Standard" equipment in my opinion.
PM me if you have any questions. Would be willing to help as time permits.
Thanks,
