Well, from my point of view it current code is a bit fragile regards
to signals. Maybe it would be nice to use signalfd() and check for
signals together with changes on master/slave file descriptors by
select/poll. But this is not so important for your plans.

OK.

Hmm.. "Every program attempts to expand until it can read mail. Those
programs which cannot so expand are replaced by ones which can."
I like git concept: here are files and it's your problem to transfer the
staff over the network. You can use rsync, http, ssh, ...
Maybe all you need is to store timing and typescript data to the one
place (e.g. /var/log/typescripts/user/<timestamp>.{session,timing})
and use ssh or so to transfer the data to another place.

Seem like overkill.

Yep, but we have generic solutions like ssh, again see git.
