Hello all! I was searching around for some example code to build a simple http server and client so that we could try to pass info between the front and middle, and found an excellent example: http://www.mems-exchange.org/exchange/software/microscope/. It's a remotely controlled mircoscope with a streaming dialog exchange (check out the network protocol link). Neat, I think I'm going to mine it as a model for our dialog. Brad
