I'm not worried that the passphrase will be guessed, and I'm completely aware
of social engineering techniques. Vulnerabilities are something else - but
keeping my system up to date is a reasonable precaution. I know that some
poor soul gets caught on day1 of a vulnerability being known - I've forgotten
the name for this - but that's just something that I have to accept. Do all I
can, then stop worrying.

But they have to get in first. I'm reasonably confident that they won't -
accepting that no-one can ever be 100% certain.
In the past I have bought time on hotel systems rather than use a laptop on a
public network for this job, but if you consider that an hotel employee could
be a security hole, you are really no better off.
