[aprssig] Too many digi's ?

I've been speculating to myself that maybe we don't have enough  
digis.  If we got the existing digis down to a reasonable HAAT,  
thereby reducing the cell size, and added more digis we might get  
both better coverage and better control of the traffic. 3000' HAAT  
may be great for a voice repeater, but I suspect it isn't all that  
great for a digital network node.

Maybe the high-site digis should be set so that they don't repeat a  
packet unless it isn't repeated by someone else in a reasonable time,  
thereby leaving the high-site digis to do fill-in and backup work.

I don't have any data to support this, but I wouldn't mind seeing  
some numbers or simulations or tests to convince me one way or the  
other.

Random thought before my caffeine takes effect...
