If you use pull you get the administration on one box. If you push you will
have to run something on both boxes I think. The problem with this is that
that user will have access to an awful lot of machines which is not wise if
you are being paranoid.

You could burn them to a read only disk but this would be a pain in the ass
making sure the disk was in every night. Are you trying to run your crontabs
from a seperate machine or check them.

Is there any way that they can be encrypted on the disk and s/ftp'd when
polled from another box.

I would be intereested in hearing what people do to get around this sort of
problem as well.
