I'm sure someone more knowledgeable than me will reply, but can't you have
a local storage drive on the laptop and an associated storage group,
making sure that all recordings on the laptop go into that storage group
(i.e. get written to the local drive).

Then "all" you would need to do is create a cron job (outside of myth)
that would copy the files from that storage group to a storage group that
lives on your lan.  I'm sure I've heard people say that myth searches all
storage groups for recordings so you are free to move the files around as
you please.

All you'd have to do is make sure your script didn't try to move an
in-progress recording which must be do-able...

Actually, isn't there some kind of event system in myth that you can use
from the python(?) api, so you could trigger a copy on a "recording
completed" event (assuming such an event exists?)
