Well, sort of. Do remember that everyone with V6 had to have a license, which
at that point you could _only_ get from Western Electric. So every
_institution_ (which is not the same as every _machine_) had had to have had
dealings with them. However, once your institution was 'in the club', stuff
just got passed around.

E.g. the BBN V6 system with TCP/IP:


I got that by driving over to BBN, and talking to Jack Haverty, and he gave us
a tape (or maybe a pack, I don't recall exactly). But we had a V6 license, so
we could do that.

But my particular machine, it worked just the way you described: we got our V6
from the other V6 machine in the Tech Sq building (RTS/DSSR), including not
only Bell post-V6 'leakage' like adb, but their local hacks (e.g. their TTY
driver, and the ttymod() system call to get to its extended features; the
ability to suspend selected applications; yadda, yadda). We never saw a V6
