Did a search here and on some search engines and did not come up with what I am looking for. Is there a program or service out there that can monitor the amount of unique visitors (based on a 24 hour or 48 hour period) and report back per day, month and year.

Another feature that I am looking for is that I can monitor more than one site through the same control panel, do not want a serperate password and login for each site.

The free webtrends software is nice for this.
