Looking at the volunteer page at <a href="http://tor.eff.org">tor.eff.org</a>, I spotted this:<br>We need an official central site to answer "Is this IP address a Tor
server?" questions. This should provide several interfaces, including
a web interface and a DNSBL-style interface. It can provide the most
up-to-date answers by keeping a local mirror of the Tor directory
information. Bonus points if it does active testing through each exit
node to find out what IP address it's really exiting from.<br><br>I already have a list of servers and their listed IP addresses. It wouldn't take much to add in some things to test what IP address is actually used when exiting.
<br><br>What kind of format would a web interface to this have? Just a textbox where you enter an IP?<br>
