I think that there should be a pseudo-cron service built into WP.  
events could be loaded up with scheduled times.  As soon as the time for 
the post's display comes around, and the first person loads WP, the 
cron's scheduled time will be earlier than the current time, and the 
pings/trackbacks should be fired off.  This pseudo-cron could run with 
one SQL query... SELECT * FROM `wp_cron` WHERE `time` < '$now';

I agree that firing off trackbacks to a non-existent entry is bad.  In 
fact, it's behavior that will get you blacklisted in many places.
