Let's say you used your BB a lot during the day but not you PB and you needed to make a few calls and weren't near a plae to charge. Would it be possible to use your PB to charge your BB? Or vice versa? I'm talking about in upcoming models as I'm sure some tweaking to the hardware would be needed.
Edit: I should also add that you should be able to select a certain amount of power to send over.
I also know that there are battery packs that pretty much do the same thing. But why have to buy one if you can use your PB to do it?

I'm pretty sure the USB On-The-Go protocol specifies that it can provide power to a slave device. So if/when RIM adds USB OTG support to the PlayBook, it technically should be possible.
