Watch, Spy, whatever you wanna call it

[Brendan Kehoe]

 Ok, I've seen this posted on and off for a few years now and I've neither heard
nor seen any definitive responses to it. There's a program available for VMS
that my managerial counterpart has great joy in showing off to me whenever he
gets the chance -- it's called Watch. (It's also a part of the Snap package.)
It, with a few privs, will let ya view a person's terminal as though you had
the same one as him/her, and it'll also let you become interactive with it,
as though it were them typing.
 Now, realize this is just for system admin purposes! (cough)
 Well, anyway, what's the deal? Has one ever been written for under Unix? (With
the plethora of hackers [old definition, not vernacular] that have and are in
the Unix world today, I'd be really surprised if it hadn't.)
 Ok, let's say it hasn't. Then how about what it'd take to write one? I can
think of a little theory (sharing their device buffers, etc etc) but I can see
that I'd probably know more internals (how oddly appropriate) than I would
ever want to if I were to sit down and do this (preferably not alone). But
that may not be that bad.
 Whatcha think?
