We run a network with a large number of PC using the Sun Microsystems
PC-NFS software.  I am interested in being able to write or obtain
some form of TSR that we can use as the basis for a very simple
messaging system.  Due to the single process nature of a PC the
process must be able to check for messages periodically or be awoken
when a message arrives.  The latter can probably be achieved using
the PC-NFS toolkit, but applications written with it tend to be
rather large and that would not be desirable for a TSR.  The former
technique is what we had in mind.  By 'watching' a file on a network
drive it ought to be possible to detect the arrival of a message in
that file and to then display it.

I had thought that a clock based TSR would work, but I don't really
want a message popping up in the middle of a graphics application.
Another thought was to try do the check everytime an application
returned to COMMAND.COM or whatever shell the user has, but I am not
sure how this is best achieved.

Has anyone already written something like this, if you haven't but
have thought about what conclusions did you reach.

Any help would be appreciated.
