may be outside the Freedom Box's threat model, in which case it's
totally fine to leave this problem unsolved, but it seems to me that
an ISP or government could write a filter rule to block
PGP-authenticated TLS traffic without blocking CA-authenticated TLS
traffic.

If I remember right, the Iranian government did something similar to
distinguish Tor traffic from other TLS traffic by looking at the
certificates exchanged during the TLS handshake.

Cheers,
Michael
