wclew,
there is another method if your already in your ftp client. I only know how to do it via PHP though, and it does involve some familiarity with your FTP client and CHMOD commands.
PM me if your interested.
The output I get from my personal site is like this, based on a PHP file i have pulling variables off the visitors. It's a pretty common way of grabbing useful info from visitors:
Date: January 25th 2004, 10:09PM
IP: 64.68.82.170
Agent: Googlebot/2.1 (+http://www.googlebot.com/bot.html)
URL: None
Referrer: None
Username: None
I've never used the "revisit after" tag and googlebot visits at least once a day, sometimes up to 20+ times a day from different IP addresses, so I don't think that meta tag has anything to do with the bots visiting.
