Well, hrm, that sucks. With the vulnerability (not really news) posted
on 
slashdot, I'm afraid that script kiddies will soon have simple tools to
DoS 
802.11, and PCF could be a simple workaround for that.

The ACLU is good because it uncompromisingly defends certain parts of
the 
Constitution, the NRA is bad, because it defends other parts of the 
Constitution.
