Just a point of clarification here about OSPF.  The protocol will find 
multiple equal-cost paths.  Whether or not a router can use this
information to load-balance in a round-robin way depends on how
the IP forwarding module in a particular implementation is implemented.

In general trying to do dynamic load balancing in a multi-vendor
environment is a pretty dicey issue.  BBN went through great pains
to tame the dynamic load balancing in their PSN networks.
