I'm aware that yes, it would have to drop some audio. I don't
personally mind that. I'm happy to say that it ought not be the default
mode of tunnel, in that it should recover all the audio eventually, but
for cases like mine, I would much prefer to have it drop audio to keep
that latency down. Perhaps an option to tunnel to say "it's OK to drop
frames"

Could even have a mode whereby if it detects silence (e.g. the
inter-track gaps in music) it will drop the "silent" frames to keep the
latency down to a reasonable level, only resorting to dropping
non-silent frames if the latency becomes higher than some larger
threshold.
