As with any products, it depends on the manufacturer. Some are very 
proactive, and addressing security in a prudent manner. Others are 
counting on FHSS being mysterious, and beyond the comprehension of 
anybody but their elite group of techies, touting "complex and 
proprietary" as their safeguards.

Not "easy" per se, but with the same equipment it'd certainly be doable. 
You won't find any $80 wireless NICs for these at your local computer 
store though. You'd have to WANT to get them, and be willing to spend 
some bucks to do it. Even then, if they're prudent and encrypting etc., 
it might all be for naught.

Google away. You should find plenty.

Proxim for one. I'm tired and busy on other things, so others aren't 
jumping into my head, but there is no shortage of them out there.
