I’ve only begun to scratch the surface on this one, so perhaps someone can save me a lot of digging with a quick answer:
Is the XBee equipped to allow communication with Maxim 1-Wire devices either via the DIO pins or (preferably) some bizarre TX/RX loopback configuration?

I don’t think so. Primary communication with the XBee is via TTL serial. Even using the digital pins in link mode, I don’t think you could reliably get the timing right plus one-wire requires you to switch the same pin to either input or output. You are far better off to put a small microcontroller between the XBee and the one-wire device.
Well that’s a real bummer. However, I guess I can still get compact units deployed with just the extra cost of an ATMega168 and a crystal. Since I already have 3.3v regulated, I’ll use 8MHz.
Unfortunately, this will increase the size of the package and the amount of power it consumes.
