i dont think that you can do with bonding what you want, because you 
just connected them to a switch
you can only bond interface together which are bonded on the opposite 
site too

so your local eth0 and eth1 is bonded and the remote site input must be 
bonded too. a switch cannot bond, a switch only switches, so it outputs 
the same packets on all ethernet connectors
so

remote:                                        local
bond0 --- eth0   ------------- eth0 --- bond0
       |  ---- eth1  ------------- eth1 --- |


i hope you understand what i mean. so bond0 is the local usable 
interface on each site which splits the traffic on 2 ethernet interfaces 
depending on your bonding algorithm. a switch only duplicates packets
