Interesting use case!  Maybe we can formalize this into one or more 
extensions, so you can just call the appropriate functions.  Here are 
your current problems which must be addressed:

* is_ip_registered() is too imprecise, as it only takes the IP as input, 
while you'd want to match the URI and port as well.
* is_contact_registered() is too precise, as it matches _everything_, 
including URI parameters which you'd like to skip.

I've put this problem on the bucket list for 3.2 :)  Cheers!
