[CQ-Contest] You gotta let me know, should M/M Distributed stay or g

[Mike Smith VE9AA]

I am all for it, but I wonder how you can honestly manage a BIG distributed 
 (internet interfaced) M/M with multiple stations per band and have "real"
TX 
 lockouts? (Internet delays, remember)

 Phrased another way, how you do prevent, say, three stations (1 run + 2
mult hunters)

using  the same callsign, but in various locations around a single country)
in one

same distributed M/M all being on 20m (and  transmitting SIMULTANEOUSLY) 

when frequency resources are slim? (are there such things as Internet tx
lockouts in "M/M D"

Recently I viewed a very short youtube demo video of something like this but
was left 
 with more questions than answers. 
 
 I don't compete against M/M's, but I do have concerns over band "real 
 estate"....ie: if everyone was doing an internet/distributed M/2, M/S and
M/M 
 using 3 or 4 QRG's each, where would the single ops set up shop? 
 
 Inquiring minds,
