Assuming the Apple USB keyboards are 2.4 GHz wireless and generate the
standard HID (Human Interface Device) report, yes (probably).

A built-in hub isn’t fundamentally different than an external hub.  The same
firmware will support both.  I use a keyboard / mouse combo (i.e., a
separate keyboard and mouse which share the same wireless dongle).  I even
have a $20 credit card sized iPazzPort 2.4 GHz keyboard with a built-in
*gyroscope*.  It appears to the PX3 (via the Arduino microcontroller) just
like any other keyboard and mouse.  

I also heard from a member whose gaming keyboard didn’t work with the P3 /
PX3.  However, I’m not sure what the exact constraint was.  In theory, hub
support *may* address this situation as well.  No promises.
