This is the tricky part. You want to divide a net in high current and
low current parts. This calls for modifications in the data structure.
The current data structure assumes that every segment of a net is
equivalent.

I have yet to see an autoplacer that is not "very weak" ;-)
If full fledged autoplacement is too hard, then how about some human
assisted solution? Say, you manually group components on the schematic.
And pcb places these components in nicely divided groups, rather than in
one large lump.
