In 2005, Google launched its Google Talk platform. Google Talk has an OTR mode that promises to not store the contents
of an IM session. Users must trust Google to follow through on this promise since there is no cryptographic assurance that the policy is enforced. PFC could be adopted to work with Google Talk. An OTR mode could be supported by having PFC turn
on the OTR flag in Google Talk so that the encrypted PFC messages are not retained by Google.
