Yeah, my naive implementation thought experiment was oriented towards a side channel brokered by the ssh connection using nginx and curl. Something like source opens nginx to share a file and tells sink via ssh to curl the file from source with a particular cert.

However, I observed that curl [0] uses openssl' quic implementation (for one of its experimental implementations). Another backend for curl is Quiche [1] which has client and server components already, has the userspace crypto etc. It's a little confusing to me, but CloudFlare also has a project quiche [2] which is a Rust crate with a CLI to share and consume files.
