Navy used to allow you to install a software PKI key on your personal computer which eliminated the need for the reader & CAC card. They just announced they are doing away with that, so no more email on the road (I'm not going to carry a reader around with my laptop

)
I have the software and CAC reader installed on my home PC (serial, not USB)...it works as is, so I don't ******* with it.
Actually the benefit of doing this is that you get the FREE symantec antivirus and firewall package for any computer that connects to the .mil stuff
