This will work for small numbers and infrequent refreshes. But imagine you need
o check every 10 secs, and you have 300 clients? Causes both locking problems,
ad problems with purging, and guranteeing that everyone "knows".
I am developing a system which uses TCP/IP to notify they other clients in a
sysem. Basically you call a method (or if you use Delphi, the TTable will do it
atomatically) and the method triggers an event, and passes message text to all
th other machines in the "system".
