Besides LACP, which behaves as described...
There are also multipathing protocols, which behave as desired.
I don't know precisely how it works, but it's something like...  Suppose you
have 2 servers, each with 4x 1Gb ports.  You configure a separate IP address
for each port.  You somehow configure server1 to know that all 4 of these IP
addresses belong to server2, so server1 will "stripe" all its data sends
across 4 interfaces.  Naturally this needs to be supported at both the
sender and recipient.

I really know almost nothing about this.  But these google terms might be
useful...  ecmp, lbmp, comstar multipath, 
Also, if you go to

ion_Control_Protocol
Then scroll down to the "See also" section.  Maybe useful.
