This is all nice and dandy but don't forget that the network has N kinds 
of "electrons", which are attracted to N end-points independently of each 
other.

The reason why Kirchoff's laws work for steady-state electrical networks 
(or networks of pipes carrying gasses) is that all particles are the same, 
and repel each other.

Packets can be made to "repel" each other, but making them drift in any 
direction where the "pressure" (or potential) is lower makes the network
useless - as it's whole purpose to move the packets to the destinations, 
and not to the places where there's no congestion.
