Those are some good suggestions, but unfortunately the service does run in 
a different application, in order to allow another group to hook into the 
service.

I do have the TCP/IP implementation up and running, and it seems to reduce 
the peak delay from one or two seconds down to 10s and 100s of 
milliseconds, but I am continuing to improve this.
