Will Leopard’s Time Machine backup to a network drive?

LeopardtimemachineappleI caught the very long and very informative Guided Tour of Leopard last night. Hey, what’s a geek to do when there’s no good television programming on and you’ve burned through all the recorded eps of Star Trek: Enterprise? It’s not like we could watch BSG since we have to wait another month yet! Wait, where was I. Oh yes, the Leopard tour…

One of the features I’m most interested in is the Time Machine backup functionality. I could care less about the pretty UI, it’s the requirement for an external drive that has me wondering. It makes perfect sense to have your data backed up to an external drive. After all: if your Mac’s internal drive fails, gets corrupt or just decides to have fun at your data’s expense, you’ll want your precious info somewhere else for the restore. When you plug in an external drive to a Leopard system, it asks if you want to use that drive for Time Machine. Very nice and very similar to how Vista asks if you want to use a flash or external drive for ReadyBoost. My question is: does that drive HAVE to be a physically connected external drive or can I use the 320 GB USB drive I hang off of my Apple AirPort Extreme router? Even more interesting: could you remotely backup and restore to a network drive at home while on the road? Seems like it should work, but I haven’t found the answer just yet…
