Not in RSX. That's a system specific thing. Not sure if RSTS/E might 
have something like that. After all, RSTS/E and VMS are more similar 
most of the time from a user point of view. In RSX there also is no 
default DECnet account.

But in RSX, it's all about how you identify yourself, and what the 
service requires. With NICE, it looks like this:

NICE is object 19. Verification says "Inspect", which means that users 
are checked up, but the information is just forwarded to NICE, who can 
do whatever it thinks is appropriate.

FAL and DDM require a valid local user, under which the service will be 
running.

Most others do not care... I can't remember what TCL is right now.

Potentially yes. Try it on some machine which have have access in some 
other way than over the network? ;-)
