Also scrubbing the data can be very hard since the information that
could be sensitive is more than user name/ip address. While there
might be some statistical information that could be picked up (hmmm
4000 users have problems with /xen installations... maybe we should
see if there is a problem with the policy and what people think they
are doing.

Another issue I could see is that if someone opted into the program,
and Fedora 'witnesses' a breakin (or some other criminal act) via a
Selinux report... what are the reporting requirements (depending on
the nation that the servers are in and where the client is.)
