Comment(by ioerror):

 We should specifically focus our audit on proxy compliance issues. timing
 information such as time zones, usernames, local host name leakage, etc

 Configure each protocol to use Tor as a SOCKS5 proxy and then check:

  * Do we only send traffic over the proxy?
  * Do we leak DNS?
  * If the proxy is unreachable - do we fail closed?

 The Pidgin we ship should disable any protocol support for information
 leaks - we should not give remote typing indications, etc.
 There are some privacy issues that are unavoidable - any plugin (such as
 OTR) allows a remote party to illicit a client response will be able to
 calculate network latency. Some protocols allow this by default (IRC),
 others have this as matter of functionality (OTR) - we have to find those
 issues identify them.
