Listen/notify implies a dynamic table that is constantly on the change. Am I correct?

The table I am talking about is completed through one interface then imported as a relatively static information base for the application in which I am seeking help.

Yes,
you would have to define a rule on the table and when the table changed it would send a notification back to who ever is listening.

Why don't you just run a query against the table, then loop through the result set and then trigger your devices from inside the loop?

myquery.sql.add('select * from mytable where bla = bla;');
myquery.open;
While not myquery.eof do
  begin
if myquery.fieldbyname('somefield').asstring = 'something' then
          //signal your device.
         myquery.next;
  end;

I guess that is the best I can come up without knowing more.

Later,
