If the 10-minute rule creates so much concerns for so many people, why do we need expensive and time-consuming hi-tech solutions when low-tech ones are available?  All that is needed is to include the time (the 2-digit minute is enough) of the previous QSO in the exchange and the problem is solved. In addition, making the exchange different that your zone or state or whatever known piece of data adds a challenge and makes the contest more interesting.

The log will look like this:

QSO: 14001 CW 2009-07-11 1411 N2WQ/VE3      599 0004     VY2ZM         599 1109        
QSO: 14001 CW 2009-07-11 1412 N2WQ/VE3      599 1104     K4ZW          599 1208        
QSO: 14002 CW 2009-07-11 1413 N2WQ/VE3      599 1204     K3WW          599 1308        
QSO: 14002 CW 2009-07-11 1413 N2WQ/VE3      599 1304     K4RO          599 1308        
QSO: 14003 CW 2009-07-11 1414 N2WQ/VE3      599 1304     K6RB          599 1306        
QSO: 14009 CW 2009-07-11 1417 N2WQ/VE3      599 1404     W0SD          599 1607        
QSO: 14010 CW 2009-07-11 1418 N2WQ/VE3      599 1704     N7BV          599 1706        
QSO: 14011 CW 2009-07-11 1419 N2WQ/VE3      599 1804     K4BP          599 1908        
QSO: 14015 CW 2009-07-11 1421 N2WQ/VE3      599 1904     VE9HF         599 2009    

So if somebody wants to cheat, they can't hide the difference is the time because they have sent the time to somebody as part of the exchange.

I am sure this is not bullet-proof, but significantly easier to implement than a network of SDRs around the world, requiring logs to be sent NN minutes after the contest end, webcams, etc.
