Joe,

Cisco's Content Engine can also do the functions that Scott
mentioned, plus gives you the benefit of web caching.  It's 
very feature-rich, and the command line looks a lot like IOS.

You can configure it to FTP your whitelist of URLs, and set
up user-specific or global time restrictions, which address
a couple of your specs.  For the latter, I think you need
the Smart Filter module, which is not part of the basic 
Content Engine distribution.
