Hi Dan,
        If we replaced Sed with Cat, I'm a little confused as to what we would 
be catting; there's a stream coming in, right?

To your second question - yes, logging is fully functional with sudo

To your final question - no, even with a sed command that performs no actions, 
no logging information is generated.

What's the simplest case that doesn't work?  What if you take out the
whole 'sed' command and just use /bin/cat?  Does invoking cronolog with
sudo work when not receiving input piped from another command?  Does it
work with a simpler sed script?
