[ih] Recently restored and a small ARPANET was run using simulated IMP hardware.

Dave's right, the details of who and which projects went where during
reorganizations were complicated and I've forgotten much of that
detail.   I should have said that the IMP-focused and network operations
projects (e.g., DDN) of Div6 migrated over a few years into BBNCC, which
also became more focused on X.25 networking and later even SNA, as well
as selling hardware and operating networks and moving into another
building.  So it became even less likely that ideas from those
operational experiences would easily feed back into research efforts
such as Packet Radio or vice versa (I don't know if the PR project  was
still active then).
