With respect to the AppleTV profileration, Jonathan is right although 
Apple has made it much easier to do AirPlay mirroring with the later 
model Apple TVs and tablets/phones/laptops.

The "discovery" of the Apple TV is actually done over Bluetooth and then 
the mirroring is done over an ad hoc wireless network between the 
tablet/phone/laptop and the AppleTV.  In that scenario, the mDNS traffic 
snooping that the wireless controllers are doing doesn't even come into 

So barring Apple deciding to change something, it does seem like Apple 
TVs are a good, low-cost option.
