Numeric keypad emulator for MacBook Pro?

Question

I've noticed that the state of the Fn key can be read in software, rather than just being a hardware-level modifier key. How do I know this? There's the Keyboard Viewer and StickyKeys, which both treat Fn just like other modifier keys.
Anyways, you know how the new MacBook Pros don't have the embedded numeric keypad? Well what I'm wondering is if there's some software to bring this back. You know, it can intercept keyboard messages and, if a key that would normally be part of the embedded keypad is pressed, check whether or not Fn is held down. If not, it will type the normal character. If so, it will type the number. Certain programs require the numeric keypad, or are at least much more usable with it (Blender, anyone?) and it would be really nice to have something like this. Thanks!

You can install the KeyRemap4MacBook PrefPane:

...and remap the fn-key to fn-key-with-numlock, where fn-key-with-numlock enables the "missing" embedded numeric keypad on the newer MBPs.
@Tuttle - how does that help the OP? There are USB and Bluetooth numeric keypads everywhere (I've even seen them in gas station convenience stores!). There's even 'an app for that', if you have an iPhone/iPod Touch. But, the OP is asking about the embedded numeric keypad which is present on older MBPs (like mine) but was dropped with the Early 2008 models.
