I think 1M echos would be a good milestone, even if it takes several GB 
of RAM. Communicado has 14GB total, so its a good place for such a test.

I realize that it will take time to work up to that level.

But even more important than 1M is just to know how the system scales, 
and document it in the user guide along with resource needs, whatever 
the level.
