I recently did this for my NFS server.  I used the classical approach. 
The non-default outgoing interface needs to have an appropriate netmask
(e.g. 255.255.255.0) and the rest need to have a restricted netmask
(255.255.255.255).  You might run into performance issues even in this
configuration, since the interface with the broad netmask gets all of the
output.

I don't know what's up with something like Etherchannel.
