Hi Michael,
Thanks for the comments. I'm only responding to a few of them.
I'll let the BBN'ers deal with the rest ;)

In reality, it will work with any C++ element for which memcpy is a
valid copy constructor. This includes many structures and classes,
but not all.

They are mblocks "contained" in the one illustrated.
Containment has *zero* to do with scheduling; it's for managing
complexity / reuse. There is only a single mblock scheduler, and it
schedules *all* messages across *all* mblocks, nested or not.
