A little more info on this possibility.  You can get the distance- 
monitor pseudobond group in Chimera with:

from StructureMeasure.DistMonitor import distanceMonitor

and run through the distance-monitor pseudobonds with:

for pb in distanceMonitor.pseudoBonds:
	...do something that sets pb.radius based on pb.length()...
