Paul,
You certainly  pose a good question, but I believe 100000 mil is the limits
of Protels workspace. What happens outside of the workspace is anyone's
guess.  I have connected 50- 60 designs a year with thousands  of
connections each, multiply that  times 5 years  and I have only ever had one
drc error from connectivity.  It was attributed to polygons which  I won't
cover here.
My recommendation is move your design to area under  50000 x 50000.
everything will work fine,   The DRC is bulletproof.   I make sure designs
are under 50 inch because Spectra will crash if the design is out of limits

Good Luck
Mike Reagan
