Very odd -- I would definitely think that it would be hard-coded on
the device.

Anyway, I'm not sure putkey and delkey are the right commands for
changing that.  But since you probably don't have tons of Bluetooth
devices around the house, a bogus MAC address is no big deal (so long
as the device actually works).

I'm waiting on mine too.  Hopefully Roger will use a reputable shipper... :-)
