Reading that made me imagine a Rube Goldberg machine for waking up a machine
from standby that doesn't support WoL.  The gist of it was using
IP-over-carrier-pidgon to send a WoL packet to a drop-box at the office.  The
weight of the paper that the packet was printed on would trigger a series of
mechanical eccentricities to send a message across the office, ultimately
ending in a robotic hand that jiggles the mouse (or taps the keyboard),
thereby waking the machine up from standby  (even better if it was a laptop
that needed to be opened); all of which together would cost orders of
magnitude more than just upgrading the workstation in question.
