We put together an initial draft describing how to bind public metadata to VOPRF used by privacy pass https://tools.ietf.org/html/draft-iyengar-cfrg-voprfmetadata-00 by binding the metadata to the keys used by the VOPRF. This is based on the scheme described in https://research.fb.com/privatestats. I've sent a mail to CFRG requesting some time. Happy to discuss this further if anyone has questions / feedback. Subodh
