It should be possible.  Read http://httpd.apache.org/docs/env.html it states:

    Access to the server can be controlled based on the value of environment
    variables using the allow from env= and deny from env= directives. In
    combination with SetEnvIf, this allows for flexible control of access to
    the server based on characteristics of the client. For example, you can
    use these directives to deny access to a particular browser (User-Agent).

I've not tried it but it certainly sounds possible.

On the other hand, there's a reason that it's recommended to run apache 
without DNS resolution turned on, DNS can be _very_ slow!
