Could sysfs be used for the bonding UI?  Seems like a natural fit.
Something like:

1) load bonding.o

/sys/class/net/
                        eth0/
                        eth1/
                        add_bond                << write-only file added

2) Create a bond:

# echo "some params" >/sys/class/net/add_bond

/sys/class/net/
                        eth0/
                        eth1/
                        bond0/
                                del_bond
                                add_if
                                del_if
                        add_bond

3) Hook up the bond:

# echo "eth0" >/sys/class/net/bond0/add_if
# echo "eth1" >/sys/class/net/bond0/add_if

/sys/class/net/
                        eth0/
                        eth1/
                        bond0/
                                -->eth0/
                                -->eth1/
                                del_bond
                                add_if
                                del_if
                        new_bond

4) Delete the bond:

# echo "byebye" >/sys/class/net/bond0/del_bond

Etc.  The whole kobject API is so clean, this should be trivial to code
up.  Seems like VLAN and bridge modules could follow.
