Without wishing to detract from the original poster's question, I have a 
related one.

I once looked at doing this with some non-Foundry kit and some Linux box a 
while ago: the client wanted to aggregate 4x 1Gb/s links for greater 
bandwidth (but not pay for 10Gb/s :).  Unfortunately, the connection over 
that link was pretty much from one client to one server (the latter was 
connected at 1Gb/s), and while the Linux client seemed to understand 
various modes of operation to spread traffic across several physical 
links, the other_vendor equipment didn't support it in the 
single-connection scenario: the connection was assigned a link based on 
various combinations of src/dst IP/mac, but only one link was selected for 
any particular combination.

I'm a bit hazy on details now, but given the scenario of a single client 
trying to multiplex essentially one traffic stream to a single server over 
aggregated links, would that have been doable with a Foundry device?  
Something about "mode 0" at the Linux end rings a bell.
