"So what we're talking about now is whether it would be worth sending   
frequency data from the K3 to the KAT500--at the time of keying--over   
either the auxBus or the RS232 port. The answer, IMHO, is no. In   
either case it would take approximately the same amount of time to   
send the data as it would for the KAT500 to do RF sensing of the VFO   
frequency. "

Well, if at at key time the KAT500 already knew the new frequency it could
update the relays immediately without measuring the frequency. If this takes
5-10ms, the normal keytime to RF output time delay should prevent hot
switching of the relays. What this means in practice is that operators could
go right ahead with full power.
