Two Top-20 features sought for UNIX

[Susan E. Cole]

I like UNIX better than Tops-20, really, but there are two Tops-20 capabilities
that I wish I could get on my Pyramid system.

One is "advise", which allows a user on one tty, with permission, to
share control of another's tty line.  User A "advises" user B.  Then
input to user B's job can be given from either person's terminal,
and output for B goes to both terminals.  This is very handy for
telephone consulting -- clears misunderstandings up fast.

The other capability I'd like is called "trap file openings" on Tops-20.
Once you set this feature on, the system announces every file open
done on your behalf (and whether it is for reading or writing).  This 
can also clear up confusion real fast -- "it's looking in THAT directory?!"

If anyone knows how to implement these features on UNIX, whether with public
domain or purchased software, please post or mail.  Thanks very much!
