Stay tuned, it will change by tomorrow if not sooner.

Based on the interchanges over the past couple days it seems that a several basic ATLAS candidates have arisen:
 
 
2 layer
No LVDS on PCB
 
Arguments for:  less expensive to fab
                        LVDS can be distributed with twisted pair cables
                        Fewer or no termination issues
 
 
4-layer
4 LVDS lanes on board
 
Arguments for: LVDS lanes make it more general purpose for future applications
 
 
 
4 slot
 
Arguments for: Fits in 4 slot Aria case
 
6 slot
 
Arguments for: We?ll probably need more than 4 slots eventually
                        More general purpose appeal for other applications
                        Don?t need buss extender boards
 
There are probably other arguments for each case which I haven?t captured.
 
So it seems we need to come to concensus on which fork to take.
From my perspective I?m thinking the 2 layer 6 slot variant makes the most sense to me.
 
Let the comments/suggestions/arguments flow?..

I fail to see why doing the same thing over and over and getting the same results every time is insanity: I've almost proved it isn't; only a few more tests now and I'm sure results will differ this time ...
