Live visitor analysis for multiple sites

We host many websites across several hosting companies. I need an application to allow our clients to login to a secure extranet on our site and see the amount of visitor traffic they have received over a particular period. *(The extranet on our site to be hosted with [login to view URL])* **Other requirements are:** What search phrases from what search engines obtained the most visitors? When did a particular search engine last visit and what pages did they spider (A frequently-updated list of IP addresses for Spider identification is avail) Clients should only be able to view stats for their own site Data should be (A-Z) sortable in the browser, for each column of data Ability to change dates in order that traffic can be viewed just on a particular date It should be possible to export the reports in Excel & to email them from the site to a user-specified email with their own subject & comments. The exported/email report should have our logo, dates, client logo & details The log files produced by each site will be identical in format *(despite being hosted with many companies)* For new clients, we need an admin tool to allow us enter ftp details & location of new log files as well as new domain name & username/password Full implementation of this system is also required. Please look at the functionality avail on [login to view URL] for their webmaster accounts. We don't mind what language is used to produce this application, php, cgi, etc If you know of software that can do some or all the above, please let me know! Thanks for your interest.
