Why not just cvsup/buildworld/buildkernel nightly, and monitor the FreeBSD
security advisory list.  When a security problem is found, you only have to
installworld/installkernel, which is usually pretty quick.

Install portaudit, which will include nightly audits of port problems in your
daily run email.  This takes the guesswork out of when to upgrade.  By cvsupping
the ports nightly, you only have to run portupgrade to get things updated.

Because of the dependencies in ports (which can get rather complex) I wouldn't
recommend automatically doing much with ports.

BTW: the "automatic upgrades" thing that Mac and Windows claim is a lie.  First
off, it doesn't include installed software, so you can't compare it to ports.
Secondly, most large companies that I'm aware of do NOT install Windows updates
until they've tested the changes in the lab to ensure that said changes don't
break more than they fix.  On that count, I think FreeBSD is just as good, or
better, than Windows or Mac.
