Handy.

However, the point is moot, as the client's site *does not permit
outbound SSH*. (Unless, according to their admin, you run an ssh daemon
on port 80, at which time it lets that through happily).

They said sometimes they have people visiting to work there who have to
go to their hotel during the day to get 'net access...
