I posted a message similar to this to comp.unix.questions, but I got no
response, so I will try again here.  

I have been developing a form of remote signalling as a thesis.  i.e. a 
user/process on one machine would be able to send a signal to a process
on another machine. What my advisor would like to make sure of is 
whether or not something like this already exists.  I know that rsh has all
the means necessary to execute the actual signal, but I have been adding
some other features, like registration, where a process can associate a
name with the pid, so a remote signaller won't have to know the pid, and
password access, so a group of people who know a password associated with
the process can send signals to it, instead of just the owner.

So, do you know of anything that does this, or something like this?
Does this sound like a good idea/useful tool?  I'm trying to design the
system to be as portable as possible, so it would work on the common 
machines of 'the big 5' (sun, ibm, hp, dec and sgi)

Any response would be appreciated, even something as simple as 
'You're an idiot.'

Thanks for your time,
	John
