+The idea of using L4 was initially voiced in the Hurd community by Okuji.
+He created the l4-hurd mailing list in November 2000. It does not appear
+that he got any further than simply suggesting it as an alternative to Mach
+and doing some reading.
+
+[[NealWalfield]] started the original Hurd/L4 port while at Karlsruhe
+in 2002. "My intention was to adapt the Hurd to exploit L4's concepts and
+intended design patterns; it was not to simply provide a Mach
+compatibility layer on top of L4. When I left Karlsruhe, I no longer
+had access to Pistachio as I was unwilling to sign an NDA. Although
+the specification was available, the Karlsruhe group only [released
+their code in May 2003][1]. Around this time, Marcus began hacking on
+Pistachio. He created a relatively complete run-time. I didn't
+really become involved again until the second half of 2004, after I
+complete by Bachelors degree.
+
+Before Marcus and I considered Coyotos, we had already rejected some
+parts of the Hurd's design. The resource management problems were
+what prompted me to look at L4. Also, some of the problems with
+translators were already well-known to us. (For a more detailed
+description of the problems we have identified, see our [[Critique]] in this
+month's SIGOPS OSR. We have also written a forward-looking
+[[PositionPaper]].)
+
+We visited Jonathan Shapiro at Hopkins in January 2006. This resulted
+in a number of discussions, some quite influential, and not always in
+a way which aligned our position with that of Jonathan's. This was
+particularly true of a number of security issues.
+
+Hurd-NG, as we originally called it, was an attempt to articulate the
+system that we had come to envision in terms of interfaces and
+description of the system's structure. The new name was selected, if
+I recall correctly, as it clearly wasn't the Hurd nor the Hurd based
+on L4."
