You can cast the lure as much as you want, but if no fish bites, you have 
not caught a fish.  There must be a reception event to trigger the process 
by which a QSO is conducted.  Both reception and transmission are necessary, 
but neither is sufficient.  Transmission events soliciting QSOs typically 
outnumber reception events many-to-one. (Which key on your keyboard is the 
most worn - F1 or Insert?)  Thus, reception is the critical element in 
allowing the transaction to proceed.

To quote our Vice President, "So?"  Realigning and creating categories (or 
not, should that be the decision) based on advances in technology is always 
in order.  There were no categories for power division until affordable 
amplifiers became widespread.  QRP was added when large numbers of those 
stations entered the competition.  Amplifiers and flea-power rigs had always 
existed - it was not until they created distinct populations within the 
contest community that categories for them became necessary - and useful - 
in maintaining peer-based competition.

What we are talking about is a significant qualitative advance in the 
capability of the technology, not disputing whether it has or has not been 
used in the past.  I maintain that a technology capable of extracting the 
crucial contact-initiating information from many more channels 
simultaneously than even the most skilled human can process is definitely 
worth evaluating as to whether it creates a statistically distinct 
population warranting a separate category.

There may be no line of reasoning that definitively answers the question. 
We may have to undergo a period of evaluation during which this sort of 
technology is evaluated for its effect on actual scores.  This will be 
difficult because the technology won't "hold still" long enough for a true 
evaluation, but at some point it will become clear whether multi-channel 
information extraction actually creates a new class of stations.

Using history as a guide, there are three contradictory examples: power, 
spotting networks, and SO2R.  Power differences clearly create distinct 
populations of scores.  Spotting networks have not been shown to provide a 
competitive advantage - the top SO scores regularly exceed the top SOA 
scores.  (What spotting information does accomplish is to increase scores of 
smaller stations, compressing scores upward from the bottom of the 
population.)  SO2R does increase the competitive advantage of top SO 
stations more than spotting networks, but not so much as power.  The open 
question is whether SO2R, if extended to SO-infinity-R, would cause a 
distinct population of stations to appear or is it just a limiting case of 
SOA that has already been shown not to convey the distinct advantage it was 
originally thought to confer?  We can not answer that question at this time. 
As the Magic 8-Ball would say, "Ask Again Later".

So it comes down to making a case to the contest sponsors who will then make 
a decision based on their accumulated understanding of the game, the history 
of the effects of technology on the game, and the requirement for the game 
itself to satisfy the Basis and Purposes of the amateur service.  They're 
going to have to lead this target a bit, but they're usually a pretty good 
shot, so let's see what happens.
