The "Run And Announce MONitor" (RANMON) system uses mailslots.
The user runs a program on any machine using the "ran" program.
On another machine the same user runs the monitor program (ranmon).
When the "ran" program completes it sends a mailslot packet
on the network that all copies of ranmon receive. The ranmon
program announces completion with a message box.

You must be logged in under the same account name on both machines
for this version of ranmon to work properly. It is easy to
change this behavior.
