Yep, basically I will set my key to expire one day later and push it to
the keyservers.  I will intentionally not retrieve the updated
expiration on my machines and continue to sign as usual.  And see how
long it takes people to catch on.

I've always wondered how many people would actually realize a key has
been revoked after publishing a revcert to the keyservers.  If could
undo a revocation, I'd do that instead.  But I think a expiration is a
good enough simulation.  It should cause people to raise some eyebrows
if they're refreshing their keyrings regularly.

I've already got a date picked out.  You've been warned... ;-)
