I only have one large instance live.  My impression from previously is that
between host bandwidth is generally about what you saw.  We have been able
to sustain 20-30MB/s into EC2 to a single node which should be harder than
moving data between nodes.  I have heard rumors that others were able to get
double what I got for incoming transfer.
