Skip,
Check out the section of the C# faq titled "How can I subscribe to
events exposed by a remoted object?", located at (watch for line wrap):
http://blogs.msdn.com/csharpfaq/archive/2004/04/28/122691.aspx
There is an explanation of how to get events to fire over remoting, as
well as links to samples.
Hope this helps.
