 As the protocols do not require any special privilege
 to implement, this is not an issue on the Hurd.
 
+In Mach parlance, a *translator* is what they name a *server*: a process that
+participates in [[RPC]] interactions.  In the Hurd, a translator is a server
+that is additionally attached to a filesystem node.  Thus, it is quite common,
+even in the Hurd context, to speak about *server*s if you're stressing the RPC
+part, and on the other hand about *translator*s if you're stressing the
+filesystem part: a translator implements the [[interface/fs]] and
+[[interface/io]] interfaces.  For example: *the [[pfinet]] server implements
+the socket API calls (which are mapped by [[glibc]] to equivalent RPC calls)*,
+compared to *a [[libdiskfs]]-based translator implements a filesystem, based on
+a backing store*.

 To learn how to write a translator, read the code!
 It is well documented, in particular, the header files.
 The [[Hurd_Hacking_Guide]] also has a tutorial.
