    You could use transparent proxies with user authentication.

    Um, then you should probably buy ISA- personally, I'd keep it behind
    something else, but that's probably my historical paranoia of products
    from that vector.

    If ISA does what you want, then get it- you could do authenticated SOCKS,
    or authentication to any other firewall which supports authentication
    (heck, even Apache's mod_proxy does authentication)- but if there's a tool
    that does what you wish then barring any major issues, you should use that
    tool.
