It is very hard to sniff a switched fabric.  (And this is kind of what AP 
Isolation does)  You can do some tricks, but most of them are very 
noticeable.  Generally, to effectively sniff, you need to interrupt the 
traffic some way.  If you can monitor for this, you are mostly safe from 
sniffing.
